Abstract
A retractable tie-down assembly that enables a transportable item to be secured on a trailer. The retractable tie-down assembly is assembled about a frame that is permanently attached to the trailer. Webbing or other strap material has one end which is attached to a spool that is rotatably mounted to the frame. The spool includes a pair of side walls which are formed in the shape of ratchet wheels. A handle is movably mounted on the frame and includes a pawl that is engageable with the ratchet wheels and capable of rotating the ratchet wheels and spool in its retracting direction to take up webbing onto the spool and tighten the same. The retractable tie-down assembly also includes a lock that is capable of locking the spool against rotation in its pay out direction.
