BEST 1E7430C4RP3626 – Frequently Asked Questions

1) Does the BEST 1E7430 mortise cylinder come with a core and keys?
The 1E7430 is the mortise housing built for a BEST small format interchangeable core, and the core is what carries the keying. Order the core separately so it can be combinated into your existing BEST master key system. If you need an uncombinated core to pin yourself, GMS sells a 6-pin SFIC core (IC6-26D) and a 7-pin (IC7-26D), both supplied un-combinated with keys, pins, springs and caps not included.
2) Which cam do I order for a BEST 45H or 30H mortise lock?
Cam choice is the order decision that matters most here. Seven cams are offered: C4 standard cam, C191 for BEST 30H mortise (latch), C258 for BEST 30H mortise, C210 for BEST 45H mortise, C265 for Schlage L mortise, C208 for Sargent, and C181 for Adams Rite MS. For a 45H take C210; for a 30H take C258, or C191 if you are driving the latch.
3) Is there an alternative to the BEST 1E7430 mortise cylinder housing that still takes a BEST small format interchangeable core?
Yes. The GMS ICM7-ST is a BEST-style SFIC straight mortise housing in 7-pin format with a Yale cam, so it accepts the same BEST small format interchangeable cores. The BEST 1E7430 differs in that it is ordered with a choice of cam rather than a single fixed cam - C4 standard, C181 for Adams Rite MS, C191 and C258 for BEST 30H mortise, C210 for BEST 45H, C208 for Sargent, and C265 for Schlage L mortise - and in a range of finishes including 605 bright brass, 626 satin chrome and 690 statuary dark bronze. Choose on which cam your mortise lock body needs.
4) I only need to rekey the opening, not replace the mortise housing - what do I order instead of the BEST 1E7430?
If the mortise housing already in the door is sound, order a core on its own rather than a complete cylinder. The GMS IC7-26D is a 7-pin small format interchangeable core sold un-combinated, and the GMS IC6-26D is the 6-pin version; both ship without keys, pins, springs or caps, so they are intended for a locksmith to pin to your existing keyway. The BEST 1E7430 is the whole mortise cylinder with the SFIC housing and cam, which is what you need when the housing itself is being replaced or the cam has to change to suit a different lock body.
5) What finishes does the BEST 1E74 mortise cylinder come in to match my existing door hardware?
Eight finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, 622 matte black, 625 bright chrome, 626 satin chrome, and 690 statuary dark bronze. For a building standardized on US26D hardware, 626 satin chrome is the match; for US10B trim, 613.
6) Is this a rim cylinder or a mortise cylinder?
Mortise. It is a threaded cylinder body with a cam on the back, for mortise lock cases, not a rim cylinder for a surface exit device and not a key-in-knob replacement. Commercial duty, mechanical only, no electronics.
7) I need a BEST-style SFIC mortise housing but with a Yale cam. What are my options?
The 1E74 housing is offered with C4, C181, C191, C208, C210, C258 and C265 cams, which does not include a Yale cam. For that, GMS makes a BEST SFIC straight mortise housing, 7-pin, with a Yale cam (ICM7-ST). It accepts the same small format core.
8) The cylinder sticks out too far past the trim. What do I need?
You need a cylinder collar or ring to take up the gap and set the projection. The 1E74 works with cylinder rings to adjust for different lock and trim thicknesses; GMS sells a collars kit (KIT-PART04) that covers the common sizes.
9) Can I use this to standardize keying across a whole facility?
That is the point of the interchangeable core format. One core design drops into every 1E74 mortise housing across the building, so a facility can run a single BEST master key system and rekey an opening by swapping the core with a control key instead of pulling and pinning cylinders. Order the same cam per lock family: C210 for 45H openings, C258 or C191 for 30H.
10) Will a GMS SFIC core work in place of the BEST 1E7430 on a Schlage L mortise lock?
A core alone will not, because a core is not a cylinder. The GMS IC7-26D and IC6-26D are cores only and still need a mortise housing with the correct cam behind them. For a Schlage L mortise lock body the cam matters: the BEST 1E7430 is ordered with the C265 Schlage L mortise cam for that application, versus C4 standard for general mortise work. If you are supplying a core to drop into a housing that is already on the door, confirm the housing's cam matches the lock body first.
11) The BEST 1E7430 sits proud of the mortise lock face - do I need a different cylinder?
Not necessarily. Cylinder projection at the face is normally taken up with a collar or ring, and the GMS KIT-PART04 collars kit is a cylinder collar assortment for that purpose. The BEST 1E7430 is described as working with different cams and cylinder rings to adapt it to other manufacturers' locks, so a collar is the usual fix before you change the cylinder itself.
12) What is the difference between a 6-pin and a 7-pin small format core for a BEST mortise cylinder?
Pin count has to match the master key system you are keying into. GMS offers both, the IC6-26D as a 6-pin small format interchangeable core and the IC7-26D as a 7-pin, both un-combinated. The BEST 1E7430 mortise cylinder uses the BEST interchangeable core system so it can be brought into an existing BEST master key system - check whether that system is pinned 6 or 7 before you order cores against it.
13) What holds the cylinder in place in the lock case?
A diagonal set screw seats into the cylinder wall and clamps the cylinder in the housing, which also keeps it from being spun out from the outside. Standard practice on a mortise lock: thread the cylinder in to the correct depth so the cam lines up, then tighten the set screw through the edge of the lock case.
14) What is the 1E74 housing machined from?
Brass or bronze bar stock, machined rather than cast, which is why it holds up in high-use commercial openings like schools, healthcare and multi-tenant buildings.
