HBX506 Ifor Williams The New Generation HBX Horsebox

O’Haire Trailers is proud to supply the Ifor Williams HBX506 – The New Generation HBX Horsebox.

Available in the familiar 506 size format the design comes with a streamlined aluminium body and a host of intelligent new features. These include the ability to open the rear of the horsebox as both a ramp and a side-hinged door, and the option to open the front windows fully, or just a little.

The sides, floor and ramps of the HBX range are manufactured entirely from aluminium planking. This lightweight structure provides clean modern lines, making the horsebox easy to tow without compromising on strength. The sides and ramps are all anodised to give a smooth and sophisticated finish which is easy to maintain.

The HBX range features three models – one suitable for single horse transport and two different sized double horseboxes.

The HBX-403 is a single horsebox suitable for the transport of a horse of up to 16.2hh. As a single horsebox the HBX-403 offers more stall width than either of the two double horseboxes.

The HBX506/511 double horseboxes are ideal for transporting two horses up to 16.2hh/17.2hh respectively. They are available with the option of either a front ramp or a built-in tack locker.

Options include padded breast and breeching bars, side padding and the choice of fitting a side awning to your trailer via the awning rail (fitted as standard).

Please see specifications for all models in this trailer range below.
