Dorma 9300B Rim Exit Device for 36" Wide Door
The Dorma 9300B is a heavy-duty, Grade 1 rim exit device designed for wide-stile wood or metal doors. This page is the factory B rail (36 in door), function 01 Exit Only -- no outside trim. Use it on a single door or a pair with a mullion when the opening needs a Grade 1 rim and life-safety compliance without a fire label.
Grade 1 Strength and Universal Design
Certified to ANSI/BHMA A156.3 Grade 1, the Dorma 9000 Series is built for high-traffic schools, hospitals, and commercial exits. The specification page calls for a deadlocking latch bolt with a 3/4 in throw on every 9000 device. The 9300 is non-handed -- field reverse is not a factory option. PL38 prices A, B, and C the same for the same finish; this listing is B (doors 32 to 36 in).
Advanced Security and Electrified Integration
This 9300B is the mechanical panic device: UL / cUL panic listed, not fire-labeled. F9300B (UL10C as printed for F9300) is a separate listing so a fire opening is not ordered as panic. 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
- Non-handed rim: the data table marks the 9300 as non-handed. Order rail length; handing is not a factory option on this rim.
- Single-point latching: deadlocking rim latch, 3/4 in throw, for a single door or a pair with a removable mullion.
- Grade 1 certified: ANSI/BHMA A156.3 Grade 1 on the 9000 Series certification page.
- Panic listed: UL / cUL panic and CSFM on wide stile. UL10C is the fire-labeled F9300B listing, not this page.
- B rail as shipped: 36 in device for doors 32 to 36 in (touchpad 24-5/8 in). A = 48 in and C = 30 in are separate lengths.
- Strike 463: PL38 default / no-charge rim strike on 9300 and F9300.
