Dorma F9100B Fire-Rated CVR Exit Device
The Dorma F9100B is a heavy-duty, Grade 1 fire-labeled concealed vertical rod exit device for wide-stile wood or metal fire pairs that need the rods hidden. The F prefix is the fire label, not a function. This page is the factory B rail (36 in door), function 01 Exit Only, default RHR. Panic 9100B is a separate listing. It is not 9100R-630 or 9100L-630.
Grade 1 Strength and Universal Design
Certified to ANSI/BHMA A156.3 Grade 1, the fire-labeled 9100 latches top and bottom with the rods concealed in the door. Specify 7 ft or 8 ft door height. Final hardware must match the opening fire rating and the AHJ.
Advanced Security and Electrified Integration
This F9100B is the fire-labeled mechanical CVR. A published hourly rating and UL file number are not claimed here. The 9000 order block lists factory options including MLR, ES, MS, and LM. Those options are not on this 01 Exit Only page.
Key Product Features
- Fire-labeled F9100: the F prefix is the fire label on the 9100 CVR. This page is that 36 in device, not panic 9100B.
- Concealed two-point latching: rods stay inside the door. Use when aesthetics or vandalism require the rods hidden.
- No hex-key dogging: less dogging is standard on the fire-labeled F9100.
- Grade 1 certified: ANSI/BHMA A156.3 Grade 1 on the 9000 Series certification page.
- Default B + RHR: PL38 p.91 -- Size B and RHR are the factory default when not specified.
- Default strikes included: top 418 and bottom 439. SNB thru bolts are standard on fire and hurricane rated devices.
