Ifor Williams HB511 Double Horse Trailer – Black
The Ifor Williams HB511 is the largest in the HB range, designed to comfortably transport up to two horses up to 17.2hh. Built with strength, durability, and safety in mind, it’s the ideal choice for horse owners needing extra internal space.
This trailer features a large front inspection window for greater visibility and ventilation, while the full-width centre partition allows for safe, adjustable separation between horses. The partition can also be removed to accommodate a single larger horse or to use the trailer for general-purpose transport.
Standard features include a full-width, gas-assisted rear ramp for loading, and an offside (right-hand) front unload ramp for forward exit. A rear ramp/door combination and nearside (left-hand) unload ramp are also available as special order options.
