Accentra KRM200F Keyed Removable Mullion — 7'2" Fire-Rated, UL/cUL Listed
The Accentra KRM200F (formerly Yale Commercial) is a keyed removable mullion designed for pairs of commercial doors equipped with rim exit devices. It provides a solid, lockable strike surface so each leaf operates independently while maintaining a tight, code-compliant center closure. A built-in keyed cylinder secures the mullion against unauthorized removal — when full clear-opening width is required, an authorized key releases it for rapid field removal. The KRM200F carries a 1-1/2 Hour Fire Rating and is UL/cUL Listed, making it suitable for fire-rated paired openings in schools, hospitals, warehouses, and institutional facilities.
Specifiers and facility managers looking for alternatives to a von Duprin removable mullion or a Falcon removable mullion will find the KRM200F a direct-application solution for compatible rim-device pairs for paired exit-device openings. The Accentra (formerly Yale) 6000/7000 Series ecosystem is a preferred line for stable, service-friendly commercial openings.
Key Features & Benefits
- Keyed Cylinder Security: A mortise cylinder (Accentra 2153 x 2160 cam, ordered separately) locks the mullion in place, preventing unauthorized removal and deterring theft or tampering.
- Quick Authorized Removal: One turn of the key releases the mullion instantly, providing full unobstructed clear opening width when needed — ideal for move-in/move-out, delivery access, or emergency egress management.
- 1-1/2 Hour Fire Rating | UL/cUL Listed: Tested and listed for use on fire-rated paired openings; preserves the door assembly's fire label.
- Compatible with Accentra 1800, 2100, and 7000 Series: Engineered to coordinate with Accentra rim exit devices across multiple series, simplifying specification on new construction and retrofit projects.
- Heavy-Duty Tubular Steel Construction: 2" x 3" tubular steel body with red primer finish delivers institutional-grade strength and durability for high-traffic openings.
- Requires Separate Cylinder: Accepts the Accentra 2153 standard mortise cylinder (6-pin, 1-1/8") with cam #2160; LFIC (2196/2197) options also available — U5153 high-security cylinders are not compatible with keyed removable mullions per manufacturer specification.
- Parts Availability: Replacement components — including Top Retainer Pack 60-7000-0755, Bottom Retainer Pack 60-7000-0760, and Locking Mechanism 60-7000-0750 — are cataloged for field serviceability.
