BEST 1E7422C4RP3626 – Frequently Asked Questions

1) Does the BEST 1E7422 mortise cylinder come with a core and keys?
No. The 1E7422 is the mortise housing only, built to take a BEST small format interchangeable core. You order the core and keying separately, then drop the core in. Because it is SFIC, the core can be pulled and swapped later with a control key without taking the cylinder out of the lock.
2) Which cam comes on the BEST 1E7422 and can I get a different one?
Standard build is the 1E-C4 cam for common mortise lock applications. Thirteen cam options are orderable on the housing: C4, C118, C127, C128, C129, C136, C161, C181, C191, C208, C210, C258 and C265, which is how you match other manufacturers' mortise lock bodies. Pull the cam off the lock you are replacing and match it before ordering.
3) Can a BEST 1E7422 be keyed into our existing BEST master key system?
Yes. It uses the BEST interchangeable core system and can be masterkeyed into any existing BEST system, so a facility running BEST cores campus-wide can bring this mortise opening onto the same keyway and master structure.
4) Will a BEST 1E7422 work in a rim device or a key-in-knob lock?
No. This is a mortise cylinder, threaded to go into a mortise lock body. A rim exit device needs a rim cylinder with a tailpiece, and a knob or lever set needs a key-in-lever core housing. Only use the 1E7422 where the lock case is a mortise lock.
5) Can the 1E7422 replace a cylinder in a non-BEST mortise lock?
Often yes, and that is what the cam choices are for. The housing is built for standard mortise lock applications and BEST publishes cam variations to suit other manufacturers' lock bodies, with cylinder ring options for depth. The right approach is to identify the cam shape on the existing cylinder and pick the matching cam code from the thirteen offered.
6) What is the closest alternative to the BEST 1E7422 mortise cylinder housing if I need a Yale cam instead of the standard 1E-C4?
The BEST 1E7422 is a mortise cylinder with SFIC housing that ships with the 1E-C4 cam, though it is offered across a range of cam options including C118, C127, C128, C129, C136, C161, C181, C191, C208, C210, C258, C265 and C4. If the opening needs a Yale cam specifically, the GMS ICM7-ST is a BEST SFIC straight mortise housing in 7-pin with a Yale cam. Both accept a small format interchangeable core, so your existing BEST keying can carry over to either housing.
7) I already have mortise housings in the doors and only need to rekey - do I need the BEST 1E7422 or just a core?
If the mortise housings are already in the doors and keyed correctly for the openings, you only need cores. The GMS IC6-26D is a 6-pin small format IC core only, un-combinated, and the GMS IC7-26D is the 7-pin version of the same core - both ship without keys, pins, springs or caps, so they are pinning-shop items. The BEST 1E7422 is the housing side: the mortise cylinder body with SFIC housing that threads into the mortise lock and carries the cam. Buy the 1E7422 when the housing itself is missing, damaged, or the wrong cam.
8) What holds the cylinder in the lock body - is there a set screw?
A diagonal set screw seats in the cylinder wall and clamps the cylinder in the housing when tightened, which is what resists someone spinning or backing the cylinder out of the door. Standard practice is to back that screw off before threading the cylinder in, then snug it once the cam is oriented.
9) What finishes does the BEST 1E7422 mortise cylinder come in to match our other doors?
Eight finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil-rubbed satin bronze, 622 matte black, 625 bright chrome, 626 satin chrome and 690 statuary dark bronze. For most commercial buildings the match is 626 satin chrome or 613; the body is machined brass or bronze bar stock under the plating.
10) What else could I buy instead of a BEST mortise SFIC housing?
If you are staying on the BEST keyway but want an alternate housing, the GMS ICM7-ST is a BEST SFIC straight mortise housing in 7-pin with a Yale cam. Note the difference: it ships with the Yale cam rather than the BEST 1E-C4, so confirm which cam your mortise lock body takes before you swap between them.
11) I need cores to go with these housings - what are my options?
For uncombinated small format cores you can start from GMS IC7-26D, a 7-pin SFIC core in satin chrome supplied un-combinated with no keys, pins, springs or caps, or the IC6-26D in 6-pin. Locksmiths pin those to the site's existing BEST master system. If you need the cylinder collars for varying door and lock thicknesses, GMS also sells a collars kit, KIT-PART04.
12) Will a collar kit solve a cylinder that sits proud of the mortise lock face, or do I need a different BEST 1E7422 configuration?
A ring or collar is the usual fix for projection. The GMS KIT-PART04 is a collars kit, a cylinder accessory intended for taking up the gap between the cylinder face and the trim. The BEST 1E7422 mortise cylinder is also offered with different cylinder rings alongside its cam variations for compatibility across applications, so the adjustment can be made either by specifying the cylinder configuration or by adding collars to what you already have.
13) Does the BEST 1E7422 work on a glass door lock, or is a different part needed there?
No. The BEST 1E7422 is a mortise cylinder for mortise lock bodies in commercial door hardware, so it is threaded into a mortise case in a standard door. Frameless glass door hardware uses its own strike and lock components - for example the Codelocks CL4000-RSB glass door strike box, which suits the CL4000 and CL4500 glass door locks. Confirm the door prep is a mortise pocket before ordering the 1E7422.
14) Can I standardize a building on BEST keying using the 1E7422 and GMS cores together?
Yes, in the sense that both are small format interchangeable core parts. The BEST 1E7422 mortise cylinder uses the BEST interchangeable core and may be masterkeyed into any existing BEST system. The GMS IC7-26D is a 7-pin SFIC core supplied un-combinated, and GMS also builds the ICM7-ST as a BEST SFIC straight mortise housing in 7-pin. Match pin count and keyway across the housings and cores before your locksmith pins them to the facility master.
15) My mortise lock is a Corbin Russwin classroom lever lock - is the BEST 1E7422 the right cylinder or do I need the ACSI operator?
Those solve different problems. The BEST 1E7422 is a mortise cylinder with SFIC housing that supplies keyed access to a mortise lock body, offered with a range of cams so it can suit other manufacturers' locks. The ACSI 8500 Gemini operator is a classroom-function electrified operator for the Corbin Russwin 2000 Series mortise lever lock body - it changes how the lock is controlled, not how it is keyed. If you are only replacing a worn or wrong-cam cylinder, the 1E7422 is the part; confirm the cam your Corbin Russwin case requires.
16) Is this mortise cylinder suitable for a high-traffic commercial building?
It is a commercial-duty part, machined from brass or bronze bar stock rather than cast, and it is a mechanical cylinder with no electronics to power or program. Typical uses are offices, schools, healthcare, government buildings, multi-tenant residential, warehouses and retail.
17) Can I use this cylinder on an electronic or access-controlled opening?
The 1E7422 is a purely mechanical cylinder with no electronic components. It works as key override on a mortise lock, but it does not provide any credential, audit trail or scheduling on its own. For electronic access control you would be looking at a different product class entirely.
18) Is the BEST 1E7422 an electronic access control part?
No. The BEST 1E7422 is a non-electronic mechanical mortise cylinder with SFIC housing, rekeyed by swapping the interchangeable core rather than by programming. Electronic access control programming hardware is a separate category - for instance the Alarm Lock DTMIII data transfer module with 200-lock capacity for Trilogy systems, or the Alarm Lock PCI2-U USB computer interface cable with DL-Windows software. Those manage credentials in software; the 1E7422 manages them through the key system.
