The KNAACK 7750-92 is a two-key replacement set for K792 lock cylinders used on Weatherguard Red Extreme series job site storage equipment. This part ships as a matched pair, giving technicians and field crews a ready spare or a direct replacement when keys are lost or worn. Designed to the same specifications as the original factory keys, the 7750-92 maintains proper engagement with the K792 tumbler without modification. KNAACK parts and accessories are installed by contractors, tradespeople, and fleet managers who rely on job site security hardware to stay in service.
This replacement key set applies to KNAACK Weatherguard Red Extreme storage units equipped with the K792 lock cylinder. Typical use cases include replacing lost keys on job site boxes, duplicating access for crew members, and restoring a unit to full security function after a key failure. This is a factory-matched accessory intended for use by the person responsible for maintaining job site storage equipment on commercial or residential job sites.
Designed for use with KNAACK Weatherguard Red Extreme storage units fitted with K792 lock cylinders. Confirm lock cylinder model before ordering to ensure proper key cut compatibility.
Key replacement requires no tools — insert the new key into the K792 cylinder and confirm smooth rotation before returning the unit to service. If the lock cylinder itself is damaged or seized, the cylinder should be replaced separately before using new keys. Retain the spare key in a secure off-site location to prevent future lockouts.
