1/2" Crosby S-4320 Hook Latch Kit — CR-1096609

Description Keep your Crosby hooks in service with this OEM-compatible latch kit (CR-1096609 / Crosby S-4320). The spring-loaded latch positively interlocks with the hook tip to retain chain, slings, and rigging hardware even when the line goes slack — a critical safety function on any active recovery or lifting setup. Heavy-duty stamped steel construction and a high-cycle spring handle the punishment of daily towing and recovery work. Bolt-on installation means field replacement takes minutes, not a trip to the shop.
