HB511 Double

The HB511 is likely to be the natural choice for owners with larger horses

For owners with larger horses, the HB511 is likely to be the natural choice.

Built with an aluminium frame of six vertical pillars in each corner, with additional strength provided by horizontal extrusions along the length of the trailer. The concealed frame provides a large side panel area resulting in a stylish looking trailer which is more automotive than agricultural in appearance.

The trailer features a brushed aluminium frame, lowered aluminium skirt running around the front of the trailer chassis, with sides and ramps made using composite aluminium/plywood side panels.

Being longer and wider than the HB506, the HB511 is suitable for carrying two horses up to 17.2hh.

The HB511 is fitted with a pair of side windows and a larger front inspection window, allowing more light into the trailer.

Aluminium floor and rubber matting

Aluminium floors fitted as standard. Floors are covered with a 12mm thick rubber matting, providing a non-slip surface and excellent vibration absorption.

Tough, nylon moulded hinges & handles

Tough nylon moulded pull handles, catches and hinges for increased strength and ease of use.

Security marking registration with TER

Each trailer is fitted with an ID plate which has a unique serial number etched on it. Additionally, the drawbar has a different unique number cut through it, which is virtually impossible to alter without noticeably affecting the appearance of the numbers and galvanized finish.

Lockable grooms door

Flush fitting locking mechanism, provides privacy for riders if used for changing at a show. Grooms doors can be positioned on either side of the trailer.

Centre partition

Cream padding provides a light and bright interior. Hardwearing plastic kickboards along trailer sides and rubber skirts along the centre partition provide additional protection for the horse and trailer.
