Corner protectors extend strap life and protect your cargo. Valuable cargo edges are less prone to strap and chain related damage when corner protectors are used to distribute the pressure evenly over a wider area. Straps and chain life is dramatically extended when corner protectors are used to buffer the abrasive power of edges and corners as a load travels down the road. Keep your chain or strap securely in place with the 3" slotted steel corner protector.
