As a single horsebox, the HB403 provides more stall width than our double horsebox models and offers enough headroom to take one 16.2hh horse. Being a narrower trailer, the HB403 is easier to tow and produces less wind resistance when towing.
The HB403 is ideal for transporting nervous horses that require a wider stall and may prefer to travel alone.
