11 min read Last updated: January 2026 If your tall horse keeps yanking hay onto the HB511s floor or snagging a shoe in the net, youre not alone. This guide shows you the safe, chestlevel setup that prevents tangles and keeps floors cleanexactly how to hang the haynet at 1.21.4 mand the simple kit that makes height tweaks easy. Quick Summary Short on time? Here are the key takeaways. Area: Haynet Height What To Do: Hang at chest height, roughly 1.21.4 m from the floor; use the breeching bar (1.111.32 m) as your guide and tweak for each horse. Why It Matters: Keeps hay off legs, supports natural posture, and stops feed being dragged onto the floor. Common Mistake: Hanging too low so feet catch or hay ends up on wet matting. Area: Sliding Rail Kit What To Do: Fit the Ifor Williams Internal Sliding Hay Net Ring Kit (KX0841) on postSept 2012 HB511s; slide the ring higher/forward as needed and mark favourite positions. Why It Matters: Delivers precise, repeatable net placement for different horses without extra drilling. Common Mistake: Buying or fitting the kit to a pre2012 trailer without confirming compatibility. Area: PreHang Setup What To Do: Park level, handbrake on, use wheel chocks and prop stands; inspect rings/fixings; set partition and headguard; confirm tie points and breeching bar height. Why It Matters: Prevents trailer movement and gives safe, stable access while you adjust heights. Common Mistake: Working on an unsecured ramp that can bounce under you. Area: Tie Correctly What To Do: Tie the net short at the ring/rail with a quickrelease knot; position it slightly forward and keep the tail well clear; recheck after 510 minutes. Why It Matters: Minimises loops and keeps the net stable during braking and cornering. Common Mistake: Tying to a lead rope or leaving it long enough for a foot to enter. Area: Stall & Partition What To Do: Set stall length about 1.672.05 m to align the chest with the net; remove the centre partition for one horse, fit partition and headguard for two. Why It Matters: Proper stance lets horses feed comfortably and stay balanced in transit. Common Mistake: Leaving stalls unchanged so the horse must reach down or back for hay. Area: WetWeather Care What To Do: Keep nets high and short in rain; sweep, rinse and dry rubber matting after trips; use a full cover if storing outside. Why It Matters: Prevents hay wicking mud and reduces bacterial growth on damp floors. Common Mistake: Leaving spilt hay on wet mats to ferment between events. Area: Payload & Loading What To Do: Stay within the 17001750 kg payload; keep heavy items over the axle; secure everything and use only structural rings/rails for haynets. Why It Matters: Balanced, secured loads protect handling and trailer fixtures. Common Mistake: Improvising tie points or letting unsecured kit shift into nets. Area: Ongoing Maintenance What To Do: After each trip, remove nets, inspect for frayed cords and worn eyebolts, apply anticorrosion spray to fixings, and organise spares in stowage nets/bags. Why It Matters: Keeps hardware reliable and ready for safe, quick setup. Common Mistake: Reusing damaged nets or corroded rings just this once. In This Guide What height should haynet hangers be in an Ifor Williams HB511? Is the HB511 big enough for tall horses and safe haynet placement? How do you fix a haynet hanger thats too low in your HB511? What should you check before hanging the haynet? How should you position and tie the HB511 haynet? How do UK weather and roads affect haynet height and care? What do the HB511s dimensions and payload mean for hay and horses? How do you keep your haynet setup safe season after season? Your HB511 is built to carry big horses comfortably but a haynet hung too low can undo that good design in seconds. If your tall horse is dragging hay onto the floor or getting tangled, the fix is simple, safe and affordable.Key takeaway: Hang HB511 haynets at chest height (about 1.21.4 m from the floor), align with the breeching bar (1.111.32 m), and fit the Ifor Williams sliding hay net ring kit (KX0841, 55.20) on postSept 2012 trailers for precise positioning.What height should haynet hangers be in an Ifor Williams HB511?Hang HB511 haynets at chest height typically 1.21.4 m from the floor aligning with the HB511s adjustable breeching bar range of 1.111.32 m. This keeps hay clear of legs, supports natural head/neck posture, and prevents feed being pulled onto the rubber-matted floor during UK journeys.The HB511 leaves the factory with two internal hay net rings positioned for general use, but horse height and neck length vary. The quickest way to get it just right is to treat chest height as your baseline and adjust slightly up or down to suit your horses conformation. For taller horses (up to the HB511s design limit of 17.2hh), youll almost always need the ring set higher than a native pony would. Matching the net to breeching bar height is a practical cue both aim to keep the horse secure without restricting movement.Why it matters: low nets invite feet and shoes to catch, encourage horses to yank hay down, and can leave forage sitting in damp on the floor. High enough to stay off the legs, short enough to avoid loops, and positioned forward assists balance in braking/acceleration on UK roads.Is the HB511 big enough for tall horses and safe haynet placement?Yes the Ifor Williams HB511 is designed for two horses up to 17.2hh, with 2.26 m headroom and 1.79 m internal width, so big horses have the space to eat safely from a chest-height haynet.Inside, the HB511 provides an internal length of 3.523.63 m (around 11'6"), and a generous 1.79 m width to reduce crowding and stress compared to narrower models. Headroom of 2.26 m gives tall horses room to lift, lower and flex the neck comfortably while feeding. Adjustable stall length (about 1.672.05 m per stall) and an adjustable breeching bar height of 1.111.32 m let you fine-tune the stance so the horse isnt reaching down or back awkwardly for hay. If youre travelling one horse, removing the full centre partition further increases shoulder space and makes the haynet easier to access without twisting.Ifor Williams notes the HB511s extra length and width over the HB506 reduces stress on journeys. Combined with correctly placed haynets, that space helps horses travel more quietly, particularly in stopstart event traffic or on narrow rural lanes.How do you fix a haynet hanger thats too low in your HB511?Fit the Ifor Williams Internal Sliding Hay Net Ring Kit (part KX0841, 55.20) on postSept 2012 HB511s to slide the net ring to the ideal height and position on either side. The kit includes the correct fixings and eyebolts and mounts along the front ramp/inspection door area for flexible placement.This is the manufacturer-approved way to solve low net issues on taller horses. The sliding rail means you can position the ring further forward or higher to suit different horses (or two horses of unequal height) without drilling extra holes or improvising fittings. Its designed to fit both the left and right sides of post2012 HB511 trailers; if youre unsure of your trailers age, check the ID plate or consult your service history before ordering to confirm compatibility. Once installed, set the ring roughly level with the horses chest, load, and then make a minor tweak up/down to account for how your horse stands under travel.Quick tip: Make any adjustments with the trailer on level ground and the ramp supported. If you regularly swap between a 15.2hh and a 17hh, mark your favourite rail positions with a paint pen for fast set-up before a show day.What should you check before hanging the haynet?Stabilise the trailer with wheel chocks and prop stands, set the partition/headguard as needed, and confirm tie points are sound before you hang any haynet. This prevents movement of the ramp and gives you safe access to set ring height correctly.Use this pre-haynet routine every time: Position the trailer on firm, level footing and apply the handbrake. Fit wheel chocks and deploy prop stands so the fullwidth, gasassisted rear ramp cant bounce as you work. Inspect the two internal hay net rings and surrounding fixings for corrosion or sharp edges; replace or move to the sliding rail (KX0841) if needed. Decide on partition use. For two horses, ensure the full centre partition and headguard are locked in and stall length set 1.672.05 m to suit each horse. For a single horse, remove the partition to maximise space and haynet access. Check the eight external tie rings are secure for safe leading, but remember: lead ropes tie outside, haynets tie inside. Confirm breeching bar height (1.111.32 m) is appropriate for your horse so the net can be aligned at chest height.For your own safety while loading and adjusting, wear grippy footwear and a hat if your horse is lively. Our customers who lead in busy show car parks rate the added visibility of hivis rider gear and the protection of wellfitted riding helmets when working around trailers.How should you position and tie the HB511 haynet?Tie the haynet short at chest height on the trailers ring or sliding rail, using a quickrelease knot, and keep the tail of the net well clear of knees and feet. Never tie a haynet to a lead rope or to anything that can drop in height.The goal is a compact, accessible net that stays put even as the horse shifts in braking or on roundabouts. Position the ring forward so the horse reaches slightly ahead, not down between the forelegs. Tie directly to the ring or rail, keep the knot neat and easy to release, and check for any stretch once the horse has taken a few mouthfuls. If youre carrying two horses, mirror the positions so each horse has similar access and balance points. After 510 minutes of travel, a quick check during a safe stop helps you confirm the net hasnt loosened or dropped.Pro tip: Protect legs for travel. Correctly fitted travel boots or bandages reduce the risk if a horse paws at a net. Explore our selection of horse travel boots and bandages to match your horses size and the conditions youre travelling in.How do UK weather and roads affect haynet height and care?In UK autumn and winter, hang haynets high enough to keep forage clear of wet, muddy floors and clean rubber matting after every trip to prevent bacterial growth. Higher, shorter nets also help reduce stress in stopstart traffic by stopping hay from being dragged underfoot.British weather rarely plays fair on show day. Rain and mud cling to boots, tails and mats; if hay is pulled down, it wicks moisture and grime fast. The HB511s aluminium floor with rubber matting offers grip, but only if its clean and dry underfoot keep the haynet up and the floor clear. After each journey, sweep, rinse and dry the matting so spilt hay doesnt ferment between events. If your trailer lives outside, a full cover keeps interior fixtures including haynet rings free from winter damp.On the road, the HB511s specification (13pin EU lighting, DATATAG security, 165R13C tyres) is tuned for UK lanes and motorways. Pair that with sensible net placement to stop horses grabbing and dropping hay as you crawl into event traffic. Ahead of colder fixtures, rug appropriately for the waiting game: quality winter turnout rugs from trusted brands help maintain comfort when loading and standing around before and after travel. And for relaxed loading, a pocket of favourite horse treats can be the difference between a smooth ramp walk and a standoff.What do the HB511s dimensions and payload mean for hay and horses?The HB511s unladen weight is 9501000 kg with a 2700 kg gross weight, giving a payload up to 17001750 kg enough for two 850 kg horses plus kit, so haynets wont tip you over limits but must still be positioned safely.Inside, youre working with approximately 3.523.63 m internal length, 1.79 m width and 2.26 m headroom. That space lets you set stall lengths (about 1.672.05 m) so each horse stands square with the chest aligned to the haynet. Hay itself is light relative to horses, but travel weight adds up: water, tack, rugs and people count toward your payload too. Keep heavy items over the axle line, secure everything, and use the internal haynet rings (or sliding kit) rather than improvising with non-structural points.Overall dimensions (around 4.654.67 m long, 2.222.27 m wide, 2.75 m high) also matter at home: plan storage space to fully open ramps and doors so you can set and adjust haynet positions safely out of the wind and rain.How do you keep your haynet setup safe season after season?Rinse and dry the rubber matting after each trip, inspect rings and rail fixings regularly, and use a full cover in winter to protect hardware from UK damp. Organise spares in stowage nets so youre never tempted to tie a net to the wrong point.Build a quick endofjourney routine: untie and remove nets, sweep hay and droppings, hose and hang mats to dry if needed, then check for frayed net cords and worn eyebolts. A light smear of anticorrosion spray on ring fixings after winter washes keeps them turning freely. Keep spare nets, ropes and gloves tidy with stowage nets or bags so you can reach the right kit fast on dark mornings.

Its a small habit that pays off in quiet, confident travellers.ConclusionSet your HB511 haynets to chest height (roughly 1.21.4 m), align with the breeching bar, and add the KX0841 sliding rail on postSept 2012 trailers to finetune position for each horse. Stabilise the trailer, tie short with a quickrelease knot, and keep floors clean the result is safer feeding and calmer journeys in all UK conditions.FAQsWhat height should haynet hangers be in an Ifor Williams HB511?Chest height, typically 1.21.4 m from the floor, works for most horses.
