It's bench tooling for a lock shop, not hardware that goes on a door. The 40-074 upgrades the vice jaws so Schlage Everest cylinders and blanks can be held and worked during pinning and rekeying. Everest is Schlage's patented restricted keyway family, which is why it takes its own jaws rather than the ones already on the bench. Sold for commercial work, and it comes in a seal tight metal box.

An accessory. The 40-074 is an installation accessory in Schlage's rekeying and pinning line, so ordering it does not get you a lockset, a cylinder, or finished hardware for an opening. If the job is changing keying on Everest cylinders you already have in the building, this is tooling that supports that work; if the job is putting a new lock on a door, this is not the part.

No. The 40-074 is the Everest-specific jaw upgrade, bought when a shop starts servicing Everest cylinders alongside conventional Schlage keyways. Everest is the patented restricted family and is what drives the need for different jaws. A shop working only standard C keyway cylinders is not solving anything by adding this kit.

It ships in a seal tight metal box rather than a card or a poly bag, which is what a mobile locksmith wants for small bench parts riding around in a truck. Everything stays together in one closed case between calls.
