OrthoVet Splints are fabricated out of a durable one piece molded hard plastic shell with a soft "Closed Cell" foam lining. The splints are fully lined for safety and comfort. Molded contours aid in comfort and less stress while healing. There is a Grip Pad on the bottom for sure footing and three Velcro straps with soft strap pads keep the splint in place for a secure fit. The splints can be adjusted or modified by trimming or heating. For heating and flairing of splints, a Heat Gun is required.
