Dorma F9300B Fire-Rated Rim Exit Device
The Dorma F9300B is a heavy-duty, Grade 1 fire-labeled rim exit device for wide-stile wood or metal fire openings. The F prefix is the fire label, not a function. This page is the factory B rail (36 in door), function 01 Exit Only -- no outside trim. Panic 9300B is a separate listing.
Grade 1 Strength and Universal Design
Certified to ANSI/BHMA A156.3 Grade 1, the fire-labeled 9300 family uses the same deadlocking 3/4 in throw latch as the panic rim and stays non-handed. Schools, hospitals, and other rated exits use F9300B when the opening needs a Grade 1 fire-labeled rim and no exterior trim. Final hardware must match the opening fire rating and the AHJ.
Advanced Security and Electrified Integration
This F9300B is the fire-labeled mechanical rim (UL10C as printed for F9300). A published hourly rating and UL file number are not printed on those catalog pages and 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 F9300: the 2024 catalog lists UL10C when the rim is ordered as F9300. This page is that device, not panic 9300B.
- No hex-key dogging: less dogging is standard on the fire-labeled F9300. Hex-key dogging is on the panic 9300 only.
- Grade 1 certified: ANSI/BHMA A156.3 Grade 1 on the 9000 Series certification page.
- Non-handed rim: order rail length; handing is not a factory option on this rim.
- Strike 463 and SNB standard: PL38 includes the 463 rim strike and SNB thru bolts on fire and hurricane rated devices.
- B rail as shipped: 36 in device for doors 32 to 36 in. A = 48 in is a separate F9300A length.
