Abstract: A cargo strap retrieval device is provided having a rotatable spool supported by a frame structure that is adapted to be secured within the side rail of a cargo trailer. The frame comprises a first upstanding member for supporting the rotatable spool, a perpendicular shelf member extending from the upstanding member lower edge and below the spool, and a step-down side rail connector member at the end of the shelf member that secures within the open cavity of a trailer side rail to support the entire assembly while in use. The spool comprises a pair of tongs along the first side of the upstanding member for supporting a cargo strap as it winds therearound, while a backside drive member provides a user with a means of input for the spool, whereby a hand crank, ratchet, or electric drill may be utilized to drive the spool as it collects the cargo strap therearound.
