The KNAACK 7750-56 is a two-key replacement set for KNAACK jobsite storage equipment. This set supplies two cut keys compatible with the K756 lock cylinder used on Weatherguard Red Xtreme series storage units. Losing or damaging keys on a jobsite delays access to tools and materials, and keeping a spare set on hand is standard practice for contractors who run multiple units or crews. These replacement keys are a direct KNAACK parts accessory intended to restore or duplicate locking function on equipped units without replacing the cylinder.
This key set is intended for use with KNAACK Weatherguard Red Xtreme series jobsite boxes and storage equipment fitted with the K756 lock cylinder. Typical users include general contractors, electricians, plumbers, and HVAC technicians who rely on KNAACK storage chests, gang boxes, or truck boxes on active job sites. This is a parts and accessories item, not a standalone lock or cylinder.
Compatible with KNAACK Weatherguard Red Xtreme series storage units equipped with the K756 lock cylinder, as specified by the manufacturer.
No tools are required to put replacement keys into service. Verify that the K756 cylinder is present on the storage unit before ordering to confirm fitment. If a key is lost and security is a concern, consult KNAACK service guidelines about cylinder re-keying or replacement rather than relying solely on duplicate keys.
