An apparatus and system for improving rope, strap, tie downs, hooks, and nets is provided. Includes a new design whereby the apparatus has a thick walled body made of nylon, aluminum, or stainless steel with a spool and center hub and axle throughout the spool body frame and handle. The apparatus uses multiple coils to automatically retract strap or rope within the spool hub. It also contains a tangential rib opposing the face wheel. The apparatus may have gears on the radius of the wheel, spring loaded slidable pawl plates, or pivotally rotatable pawls or plates which allow the proper engagement of the wheel ratchet. It may also have rope, strap, or belt that is non-cuttable and corrosion, petrol, and chemical resistant used in tie downs and nets. The apparatus may have a lockable body frame, and/or hooks that are lockable to prevent theft. |
