Falcon 1792NL-OP/HB-OP Narrow Stile Rim Exit Device - Night Latch & Hold Back | 36" | 1790 Series
The Falcon 1792NL-OP/HB-OP is a narrow stile rim exit device from the 1790 Series, built for 36" aluminum doors with 1-3/4" door thickness. ANSI/BHMA A156.3-2001 Grade 1 certified, it combines a night latch cylinder (NL-OP) - which retracts the latch without unlocking the device - with a hold back cylinder (HB-OP) that retracts and holds the latch for controlled access. The streamlined rim design means fewer parts than concealed vertical rod devices, cast metal cover plates and end caps for institutional durability, and no openings for chains or forced-entry tools. Available with an optional RX Request-to-Exit switch for access control integration.
Key Features
- Night Latch (NL-OP): Key retracts latch without unlocking the device - maintains egress security while allowing keyed entry.
- Hold Back (HB-OP): Key retracts and holds latch back for open-door traffic flow; releases on next push of the pushpad.
- Grade 1 Certified: ANSI/BHMA A156.3-2001 - rated for high-traffic commercial and institutional applications.
- Aluminum Door Fit: Engineered specifically for narrow stile aluminum storefront doors; non-handed for simplified installation.
- TD35 Strike Included: Strike supplied standard; no separate strike purchase required.
- Concealed Fasteners: All mounting screws concealed for a clean finish and tamper resistance.
- No Chain Openings: Rim design eliminates forced-entry risk via coat hangers or chains.
- RX Option Available: Request-to-Exit switch variant (RX prefix SKUs) for access control and alarm integration.
- Retrofits 2090 Series: Drop-in upgrade for existing 2090 Series crossbar devices without door modification.
