Product Details: The Bone-Style Locking Hitch Pin from Buyers Products helps protect your trailer or cargo rack from theft. The pin works in place of a standard hitch pin. Simply insert it into the receiver tube hole and lock it in place. The bone style features two 1 in. machined ends for easy gripping and added security. BLHP300 is available in corrosion-resistant chrome finish to fit a 2 in. receiver tube. BLHP350 features a longer design, compatible with 2 in., 2 1/2 in., or 3 in. receiver tubes. Both locking hitch pins work with an easy-to-grip key. The lock has a watertight cap to resist wear and corrosion.
