STRAP RUBBER 21" W/ S HOOKS. Designed for personal watercraft trailer applications, this winch strap and hook already comes with the attachment and locknut for one mounting. Its 12-foot strap has a sewn gain on the end and also a 1" x 18" "loop" strap. Your aim is to secure your machine without any risk of damage or scratches on the fiberglass surface, as the hook itself does not come into contact with it.
