Dorma 9100B CVR Exit Device
The Dorma 9100B is a heavy-duty, Grade 1 concealed vertical rod exit device for wide-stile wood or metal pairs that cannot take a mullion and need the rods hidden. This page is the factory B rail (36 in door), function 01 Exit Only, default RHR. It is not a 9300 rim, not a 9400 SVR, and it is not the hyphenated 9100R-630 or 9100L-630 strings.
Grade 1 Strength and Universal Design
Certified to ANSI/BHMA A156.3 Grade 1, the 9100 latches top and bottom with the rods concealed in the door. Catalog printed p.14 calls it when barrier-free codes, aesthetics, or vandalism require that concealment. Specify 7 ft or 8 ft door height -- factory rods are precut for those heights.
Advanced Security and Electrified Integration
This 9100B is the mechanical panic CVR, not F9100. The 9000 order block lists factory options including MLR, ES, MS, and LM. Those options are not on this 01 Exit Only page. 9100B 630 is the complete lettered device; 9100R-630 and 9100L-630 are different, cheaper strings.
Key Product Features
- Concealed two-point latching: catalog printed p.14 -- rods stay inside the door. Use when aesthetics or vandalism require the rods hidden.
- Default B + RHR: PL38 p.91 -- if door width and handing are not specified, Size B and RHR are the factory default.
- Grade 1 certified: ANSI/BHMA A156.3 Grade 1 on the 9000 Series certification page.
- Panic 9100, not F9100: the catalog fire-lists F9100 for three-hour steel fire doors. This listing is panic 9100.
- Default strikes included: top 418 and bottom 439 on the PL38 p.90 order block.
- B rail as shipped: 36 in device (cut-down minimum 28 in). A and C lengths are separate.
