Accentra KRM200FWS Keyed Removable Mullion — 7'2" Fire-Rated Windstorm, UL Listed
The Accentra KRM200FWS (formerly Yale Security) is a keyed removable mullion engineered for pairs of commercial doors equipped with rim exit devices. It provides a solid, lockable center post that gives each leaf an independent latch strike surface — eliminating the need for a fixed mullion or a coordinator. The integrated keyed cylinder locks the mullion in place to resist unauthorized removal; when full clear-opening width is required, an authorized key releases it for rapid field removal. Buyers searching for a Von Duprin removable mullion or Falcon removable mullion alternative will find the KRM200FWS is a direct-application solution for compatible rim-device pairs — DoorwaysPlus can also quote comparable options across preferred lines upon request.
Key Features & Benefits
- Keyed Cylinder Security: A mortise cylinder (Accentra 2153 with cam #2160, ordered separately) locks the mullion body against tampering or unauthorized removal — essential for high-traffic or secured-access openings.
- Field-Removable Design: Authorized key release allows quick removal when oversized loads or full clear-opening width is needed, then fast re-installation without tools.
- 3-Hour Fire Rating — UL/cUL Listed: Tested and listed for use in paired fire-rated openings; satisfies AHJ requirements where a UL-listed assembly is mandated.
- Windstorm Certified: Windstorm-certified as a component for use in UL-listed swinging door assemblies that comply with FEMA 361 and ICC 500 - confirm the assembly listing and refer to local codes.
- Wide Exit-Device Compatibility: Fits Accentra2100, and 7000 Series rim exit devices (wide-stile configurations).
- Heavy-Duty Tubular Steel Construction: 2" x 3" (51 x 76 mm) tubular steel body with red primer finish — built for institutional and commercial door applications.
- 7'2" (86") Height: Accommodates standard commercial door heights including fire-rated frame openings.
- ASSA ABLOY FlashShip Program: Ships in 1 business day under ASSA ABLOY's expedited FlashShip fulfillment program.
Applications
- Pairs of commercial or institutional doors with rim exit devices requiring a center-post strike
- Fire-rated paired openings requiring UL/cUL listed center hardware
- Windstorm and hurricane-zone assemblies requiring certified mullion components
- Schools, hospitals, government facilities, and high-security buildings needing tamper-resistant removable mullions
- Retrofit and replacement applications for existing removable mullion openings
Cylinder Ordering Note
The KRM200FWS requires a separate mortise cylinder: order the Accentra 2153 standard mortise cylinder with cam #2160 (6-pin standard; 7-pin optional). Note: U5153 high-security cylinders are not compatible with keyed removable mullions. Cylinder is not included — confirm keying requirements at time of order.
