The Keeper 4 ft. Retractable Transom Tie-Down Strap features a durable ratchet, over-center buckle, molded grip handle, and full-size S-hook with a spring-loaded gate. The tie-down is designed to secure the trailer to a boat or jet ski while restricting the amount of vertical movement during transportation. To engage, attach the hook to an anchor point, secure webbing over cargo load, pull webbing to desired tension leaving a bit of slack and rachet by raising and lowering the handle. The webbing then locks into place to secure the cargo. Included are mounting hardware to accommodate most permanent applications and a short webbing adaptor that can be attached to the ratchet for typical tie-down uses. The retractable tie-down keeps webbing neatly coiled when not in use, making it portable and convenient to store.
