BEST 1E7432C140RP3626 – Frequently Asked Questions

1) Does the BEST 1E7436 mortise cylinder come with a core, or do I need to order one separately?
The 1E7436 is the mortise cylinder housing built for BEST small format interchangeable cores. The housing accepts the SFIC core, so if you are not pulling a core out of an existing opening you need to order a core as well. A common route is an uncombinated small format core such as the GMS 6-pin or 7-pin SFIC core, then have it pinned to your system. Because the housing takes a standard BEST SFIC, it can be masterkeyed into an existing BEST system.
2) Will a BEST 1E7436 work in a Schlage or Yale mortise lock, or only in BEST locks?
It is not BEST-only. The cylinder can be set up to run other manufacturers' mortise locks by changing the cam and the cylinder ring, which is why nine cam options are offered rather than one. In a BEST mortise lock, the standard 1E-C4 cam is the one to use. Identify the cam your lock body requires first, then order the matching cam option.
3) Can I add the BEST 1E7436 to the master key system already running in my building?
Yes, provided the building is on a BEST small format system. The 1E7436 takes a BEST interchangeable core and can be masterkeyed into any existing BEST system, so the cylinder itself imposes no new keyway. The keying is determined by the core you install, not by the housing.
4) What is a comparable SFIC mortise cylinder housing to the BEST 1E7436?
The GMS ICM7-ST is a Best SFIC straight mortise housing in 7-pin format supplied with a Yale cam, making it the closest cross-brand counterpart to the BEST 1E7436 mortise cylinder with SFIC housing. The main difference is at the cam: the 1E7436 is ordered with a cam selection spanning C140, C403, C405, C408, C413, C416, C417, C428 and C431, while the GMS ICM7-ST comes with the Yale cam. Match the cam to the mortise lock body you are feeding before you choose between them.
5) I already have mortise housings in the doors and only need the core - what should I order instead of the 1E7436?
If the housings are already installed and you only need the interchangeable core, order a core-only item rather than the BEST 1E7436, which is a complete mortise cylinder with SFIC housing and cam. 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; both are supplied without keys, pins, springs or caps, so they suit a locksmith pinning to an existing system. Choose the pin count that matches the keyway and system you are already running.
6) What finishes does the BEST 1E7436 mortise cylinder come in so I can match the rest of my hardware?
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 a building already standardized on 626 satin chrome or 630-family trim, 626 is the usual match on the cylinder face since that is the exposed part.
7) Is the BEST 1E7436 mortise cylinder suitable for high-traffic commercial doors?
It is a commercial cylinder, machined from brass or bronze bar stock rather than cast or pot metal, and BEST lists it for office buildings, schools, healthcare, government, multi-tenant residential, industrial and retail. For a property manager running many openings, the value is the interchangeable core: you rekey by swapping cores at the door instead of pulling and repinning cylinders.
8) How is the BEST 1E7436 cylinder held in the lock so it cannot be unscrewed from outside?
A diagonal set screw mounted in the cylinder wall locks the cylinder into the housing, which is what stops it being backed out and pulled. That set screw is part of the cylinder, so nothing extra is needed for retention, though you should still verify your mortise lock case has the correct cylinder set screw access.
9) Is a GMS SFIC core the same thing as the BEST 1E7436?
No. The BEST 1E7436 is a mortise cylinder assembly - brass or bronze housing machined for standard mortise applications, with a cam included and a diagonal set screw that holds the cylinder in the housing. The GMS IC7-26D is a 7-pin small format IC core only, un-combinated, with no housing, keys, pins, springs or caps. A core alone will not thread into a mortise lock; it drops into a housing such as the 1E7436 or the GMS ICM7-ST straight mortise housing.
10) My mortise cylinder sits proud of the trim - do I need a different cylinder than the 1E7436?
Usually not. Cylinder projection at the face is normally corrected with a collar or ring rather than a different cylinder. The GMS KIT-PART04 collars kit is a cylinder accessory intended for exactly that, and the BEST 1E7436 is described as adaptable to other manufacturers' locks using different cams and cylinder rings. Set the cylinder flush with the trim using the appropriate collar and keep the 1E7436 for the keying.
11) Is the BEST 1E7436 an electrified or electronic cylinder?
No. It is a purely mechanical mortise cylinder with no electrical components. If you are working on an electronic access control opening, the credential side is handled by the lock or reader, not by this cylinder, which typically serves as the mechanical key override.
12) My cylinder sits proud of the trim after install. Does the 1E7436 include a collar or ring?
Cylinder rings are the adjustment for that gap, and they are also what BEST cites, along with the cam, for adapting the cylinder to other makers' locks. If your install needs to take up space between the cylinder face and the trim, plan on a collar; a collars kit such as the GMS KIT-PART04 covers common thicknesses.
13) We are standardizing a building on BEST keying - does the 1E7436 cover electronic openings too?
The BEST 1E7436 is a non-electronic commercial mortise cylinder and covers mechanical mortise lock openings, in finishes from 605 bright brass through 626 satin chrome and 690 statuary dark bronze so it can match existing trim. Openings running electronic access control need their own equipment rather than a cylinder - Alarm Lock's Trilogy line, for example, uses the DTMIII data transfer module for lock programming and the PRE2 proximity card enroller for HID and iClass credentials. Plan the mechanical cylinders and the credential side as two separate scopes.
