BEST 1E-74-22 Mortise Cylinder Housing - 1-3/8 Inch for 6 or 7 Pin Cores

The BEST 1E-74-22 is a mortise cylinder housing in the 1-3/8 inch length, built to accept a BEST 6 or 7 pin small format interchangeable core (SFIC). A mortise cylinder housing is the threaded brass shell that screws into a mortise lock body and holds the interchangeable core, the core does the keying and locking, and the housing is what carries it in the lock. This 1E mortise cylinder is machined from solid brass or bronze bar stock, accepts all BEST cores, and can be masterkeyed into any existing BEST system. It ships with the standard ring package so you can set it to the right length, and it's offered with a range of cams to match your specific mortise lock.

What a mortise cylinder housing does

This is the key thing to understand before ordering, because the housing and the core are separate pieces. An interchangeable core system splits the cylinder into a removable core (the keyed plug, pulled and swapped in seconds with a control key) and the housing that holds it. The 1E-74-22 is the mortise-format housing, the threaded type that screws into a mortise lock case (as opposed to a rim housing, which mounts behind a rim device). You supply or add the BEST-compatible core, thread the housing into the lock, and connect it to the lock mechanism through the cam.

Because it accepts any BEST core, this housing lets a mortise lock join the same interchangeable-core key system as the rest of a BEST-keyed building, so one control key rekeys it and its masterkeys into the existing hierarchy. That single-system convenience is the whole reason facilities standardize on BEST IC.

The 1-3/8 inch length, cam options, and security

The 1E-74-22 is the 1-3/8 inch housing length, which matches deeper mortise lock prep and thicker doors (the plain 1E-74 is the shorter 1-1/4 inch version for standard prep). Getting the length right matters, the cylinder has to seat flush so the cam engages the lock correctly. The housing offers multiple cam options (C161, C181, C208, C258, C265, C4 and others) so you can match the cam your mortise lock brand requires, since different manufacturers use different cams. For added security, a set screw mounts diagonally through the cylinder wall and tightens to hold the cylinder firmly in the housing, resisting tampering.

Why choose the BEST 1E-74-22

BEST is the originator and standard of small format interchangeable core hardware, and a genuine BEST mortise housing is the reliable way to put a mortise lock on your BEST key system. The solid brass or bronze bar stock construction holds up to commercial use, the diagonal set screw adds tamper resistance, and because it takes every BEST core, it drops straight into your existing keying and masterkey hierarchy. The cam choice and 1-3/8 inch length mean you can match it precisely to your mortise lock and door, and the included rings let you dial in the projection.

One thing to confirm before ordering: choose the correct cam for your mortise lock brand and verify you need the 1-3/8 inch length (versus the 1-1/4 inch 1E-74). It's supplied less core as standard, so you'll need a compatible BEST core, or add one as the option.
