Sargent SGT-F1-4264 – Frequently Asked Questions

1) Will the Sargent KESO F1-4264 rim cylinder work with a Sargent exit device?
That's exactly what the F1-4264 is built for. It's the KESO F1 rim cylinder furnished with break-off screws and a back plate positioned above the horizontal centerline, the same configuration as the standard No 64 cylinder, which is the arrangement Sargent exit devices need. If you're cylinder-swapping a Sargent rim or vertical rod device and want KESO high security in it, this is the part number. For a non-exit application the above-centerline screw position is not what you want.
2) Is the Sargent F1-4264 cylinder UL437 listed for high security?
Yes. The F1-4264 is UL437 listed and appears in the Underwriters Laboratories Burglary Protection Equipment List under locking cylinders (241 012). That listing means it resisted picking for at least ten minutes, resisted drilling of the plug and body, and resisted forced entry by driving a cold chisel or screwdriver into the keyway and applying rotary force. If your spec or your insurer calls for a UL437 cylinder on the exit doors, this satisfies it as written.
3) Can the KESO F1-4264 be keyed into an existing KESO F1 master key system?
It can be keyed into a total KESO F1 system, but only when that requirement is established at the time the system is set up. KESO F1 is a restricted, dedicated key system, so the F1-4264 keys with other KESO F1 cylinders, not with conventional Sargent keyways. Before ordering into an existing system, run the bitting through Sargent's Key Records Department so the cylinder comes correct on arrival.
4) What do I have to specify when ordering a Sargent F1-4264 rim cylinder?
Two things beyond the finish: keying and quantity relationships. Keying is a required choice of standard keying, KD (keyed different), or KA (keyed alike). Keyed alike is what you want when several exit doors in a building should open on one key; keyed different is the default when each opening stands on its own. Then pick the finish to match the existing trim.
5) How is the F1-4264 different from a standard KESO F1 rim cylinder?
Same basic construction as the standard SARGENT KESO F1 Security System cylinder, with two additions: extra hardened steel pins that resist drilling the plug or body and releasing the tumblers, and break-off screws with the back plate above the horizontal centerline. The hardened pins are what carry the UL437 listing; the screw position is what makes it the exit-device version rather than the general-purpose one.
6) Do break-off screws mean I can't service or remove the cylinder later?
The break-off screws are a tamper feature, not a permanent seal. They snap off at the head once driven so the exposed portion gives an attacker nothing to grab, while the cylinder still services normally from the secure side of the opening through the Sargent exit device. Plan on fresh break-off screws whenever the cylinder is pulled, which is standard practice on high-security rim cylinder work.
7) Is the Sargent F1-4264 a complete lock or just the cylinder?
Just the cylinder. The F1-4264 is the rim cylinder that drops into a device you already have on the door, furnished with its break-off screws and back plate. It does not include an exit device, rim latch, or trim, so if the opening has no device on it yet you're ordering the exit device separately and this cylinder to key it.
8) What finishes does the Sargent KESO F1-4264 rim cylinder come in?
Fourteen finishes, so it can be matched to whatever is already on the door: 03 bright brass, 04 satin brass, 09 bright bronze, 10 satin bronze, 10B dark oxidized satin bronze oil rubbed, 10BE dark oxidized satin bronze, 10BL dark oxidized satin bronze clear coated, 14 bright nickel, 15 satin nickel, 20D dark statuary bronze, 32 bright stainless, 32D satin stainless, plus BSP black suede powder coat and WSP white suede powder coat. On most commercial exit device work 32D or 10B is what matches the device trim.
9) Is the KESO F1-4264 cylinder suitable for a school or hospital exit door?
It's a commercial-duty cylinder, and the buildings it's aimed at are exactly those: educational facilities, healthcare institutions, commercial office, retail, industrial and warehouse, multi-tenant residential, and government or municipal. The pull for institutions is the restricted KESO F1 keyway plus the UL437 listing, which together stop unauthorized key duplication on doors that get high traffic and standardize one key system across a campus.
