Sargent & Greenleaf Type IV Pedestrian Door Preassembled Lock, Electronic Access Control, 3ft Exit Panic Bar K/LK.

That's exactly what the 2890C is built for. It's compatible with both the S&G 2740B and the X-10, the two GSA-approved combination locks, and the assembly is built to Federal Specification FF-L-2890C for SCIF openings used by U.S. agencies, DoD, defense contractor sites, and military bases. The combination lock handles the security side; the 2890C handles the door hardware and the egress side.

Non-handed. The 2890C is field reversible, so a single unit covers both hands and you don't have to pick a hand at order time. For a facility standardizing across multiple SCIF openings, that means one part number on the shelf instead of two.

Yes. The 2890C carries a 3-hour UL fire rating, and the device is listed to UL Fire 10B and 10C as well as UL 305 for panic hardware, with NFPA 101 Life Safety compliance and BHMA Grade 1. That combination is what lets a secure SCIF opening also serve as a rated egress door.

The bar assembly measures 36 inches wide, which is the standard 3-0 door leaf. Overall the device is 36 x 14.49 x 3.33 inches, so budget the 3.33 inch dimension as the amount of hardware standing off the door face when you're checking clearance against door swing, adjacent walls, or a second leaf.

All three. Multiple strike options are offered for in-swing, out-swing, and double-door applications, and the strikes are pinch-proof. The strike is heavy-duty surface mounted with an integral roller, so it takes the door in smoothly rather than dragging on the latch. The strike is the piece you choose per opening, so specify which of the three conditions you have when you order.

The outside trim is a key operated anti-spinoff design, so the handle can't be forced or rotated off to attack the lock from the exterior side. That's a specific hardening requirement on this class of door and one of the reasons the 2890C is specified over general commercial exit hardware.

Yes, this configuration is the network connected version with electronic access control built in, ordered as the 3ft exit panic bar. You still get free mechanical egress through the bar; the access control governs entry from the secure side of the opening.

They do. All ten 2890C configurations sit on the same modular platform, so door prep and installation are standardized across openings even when one door gets the 3ft panic bar and another gets a lever. For a facility manager or an installer doing a run of doors, that's fewer prep templates and one training pass instead of ten.

No. A general commercial exit device won't meet Federal Specification FF-L-2890C and won't accept the GSA-approved 2740B or X-10 combination lock, which is what a SCIF opening requires. If the door is protecting classified material, the substitution isn't a cost decision, it's a compliance one. Standard panic hardware belongs on the non-classified doors in the same building.
