BEST 1E7448C140RP3626 – Frequently Asked Questions

1) Does the BEST 1E7448 mortise cylinder come with a core and keys?
No. The 1E7448 is the mortise housing built for a BEST small format interchangeable core, so the core and keys are ordered separately. That is the point of the SFIC design: you drop a core in and pull it out later with a control key without taking the cylinder or the lock apart. If you need an uncombinated core to pin yourself, GMS sells both a 6-pin and a 7-pin small format IC core, supplied as the core only with no keys, pins, springs or caps.
2) Can a BEST SFIC mortise cylinder be used on another brand's mortise lock?
Yes, within limits. The 1E7448 can be adapted to other manufacturers' mortise locks by changing the cam and using the correct cylinder ring for the door and escutcheon depth. That is why it is offered across nine cam numbers rather than one. If you want a ready-made ring assortment for sizing the housing to the door, GMS sells a collars kit. For a Yale-cam SFIC mortise housing out of the box, GMS also makes a 7-pin straight mortise housing with a Yale cam.
3) Will the 1E7448 work in our existing BEST master key system?
Yes. Because the housing takes a standard BEST small format interchangeable core, whatever core your system is already keyed to drops straight in, so the cylinder joins the existing master key hierarchy without rekeying anything else. You are buying the housing and the cam; the keying lives in the core.
4) Will a BEST 1E7448 fit a cylindrical lever lock or a rim exit device?
No. This is a mortise cylinder, threaded to go into a mortise lock case. It will not fit a cylindrical (bored) lockset, which uses a keyed knob or lever assembly, and it is not a rim cylinder for an exit device, which mounts with a back plate and tailpiece. For those openings you need the SFIC housing made for that specific lock type, not this one.
5) What is an alternative to the BEST 1E7448 mortise cylinder housing if the mortise lock needs a Yale cam?
The GMS ICM7-ST is a BEST SFIC straight mortise housing in 7-pin with a Yale cam, so it accepts the same small format interchangeable cores while presenting a Yale-style cam to the lock body. The BEST 1E7448 ships with the standard 1E-C4 cam and is offered with cam number options C140, C403, C405, C408, C413, C416, C417, C428 and C431, so the choice comes down to whether you want to select the cam on the BEST housing or take a housing already built with the Yale cam.
6) What holds a BEST 1E7448 mortise cylinder in the lock so it cannot be turned out?
A diagonal set screw in the cylinder wall locks the housing in place once it is threaded into the mortise case. It resists someone gripping the face and backing the cylinder out. Snug that screw after you have the cylinder threaded to the correct depth for the trim, or the cam will not line up with the lock's actuator.
7) What finishes does the BEST 1E7448 mortise cylinder come in to match our existing door 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 standardized on satin chrome commercial trim, 626 is the usual match; 626 and 630 are the workhorse commercial finishes, and this cylinder covers the chrome side of that in both bright and satin.
8) We are replacing a worn cylinder on an existing BEST mortise lock. Is this the right part?
Yes, the 1E7448 is sold as a replacement part for standard mortise applications on BEST mortise locks, and with the standard 1E-C4 cam it drops in for a like-for-like swap. Move your existing core over and the keying stays as it was. Match the finish to the rest of the trim on that door and confirm the cam number on the cylinder you are pulling out before ordering.
9) Does the BEST 1E7448 come with cylinder collars, or do I need to buy those separately?
Cylinder rings are a separate item. The GMS KIT-PART04 is a collars kit, which is the part to reach for when the cylinder needs to sit flush at a different door or escutcheon thickness. The 1E7448 itself is the machined brass or bronze mortise cylinder with SFIC housing, and it can be altered with different cams and cylinder rings to work with other manufacturers' locks.
10) Will a strike or roller latch work as a substitute for the BEST 1E7448?
No - those are different parts of the opening entirely. The Cal-Royal ASA478 is a template ASA strike, the ABH 1890 Series is a roller latch with a full lip cast strike and 5/16 inch adjustable projection, and the ABH 1895 Series is a roller latch with a T strike and 1/2 inch adjustable projection. All of those mount in the frame. The BEST 1E7448 is the keyed mortise cylinder that carries the interchangeable core and turns the mortise lock mechanism, so it replaces nothing on the strike side.
11) I need to key a Corbin Russwin classroom mortise lock - is the BEST 1E7448 the right part?
Check what the lock body expects first. The ACSI 8500 Gemini is an operator only built for a Corbin Russwin 2000 Series classroom mortise lever lock body, which is the electrified operating side of that opening rather than the cylinder. The BEST 1E7448 is a mortise cylinder with SFIC housing that ships with the 1E-C4 cam for BEST mortise locks, and it can be altered with different cams and cylinder rings to function with other manufacturers' locks - so on a non-BEST mortise body, the cam selection from C140, C403, C405, C408, C413, C416, C417, C428 or C431 is the detail to confirm.
12) What do I use instead of the BEST 1E7448 on an all-glass door?
A glass door lock needs its own frame hardware - the Codelocks CL4000-RSB is a glass door strike box for use with CL4000 or CL4500 glass door locks. The BEST 1E7448 is a mortise cylinder for standard mortise lock applications in a prepped door, so it is the wrong family for a glass storefront leaf running a CL4000-series lock.
13) I have a BEST 1E7448 in hand but the sizing is wrong for my door - what else should I look at before ordering another?
Two things change the fit independently of the cylinder itself. The cam, which is selectable across C140, C403, C405, C408, C413, C416, C417, C428 and C431 on the 1E7448, determines whether the cylinder drives your mortise lock. The collar sets the projection - the GMS KIT-PART04 collars kit covers that. If the core itself is the only mismatch, the GMS IC6-26D and IC7-26D are un-combinated small format IC cores in 6-pin and 7-pin. The 1E7448 is offered in 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 to match surrounding trim.
14) Is the BEST 1E7448 a mechanical cylinder or does it need power?
Purely mechanical. There is nothing electronic in the 1E7448, no wiring and no power supply, so it is a straight key-operated cylinder for a mortise lock body. It is built for commercial duty from machined brass or bronze bar stock.
15) Is there a keyed alternative to the BEST 1E7448 for an electronic access control opening?
Electronic access control openings are managed with different components rather than a keyed mortise cylinder. The Alarm Lock DL-Windows accessories cover that side - the AL-DTMIII data transfer module has a 200-lock capacity, the AL-PCI2-U is a USB computer interface cable with DL-Windows software for programming, and the AL-PRE2 is a proximity card enroller for HID and iClass credentials running on a 9V battery. The BEST 1E7448 is a non-electronic commercial mortise cylinder, so it addresses the mechanical key side of the door only.
