Hager 4900 Non-Keyed Removable Mullion Set — 84", USP Prime for Paint

The Hager 4900 is a heavy-duty removable mullion designed for use on pairs of doors equipped with rim exit devices. Part of the Hager 4500 Series exit device family, the 4900 mounts in the center of the opening to provide each rim device with a solid strike surface — allowing two independent single-door rim exit devices to function on a double-door opening without the added complexity of vertical-rod hardware. The result is a simpler, more durable, and easier-to-service solution for wide commercial openings. At 84 inches tall, this mullion set is sized for standard commercial door heights and ships in a USP (Prime for Paint) finish, ready for field painting to match the door and frame.

Key Features & Benefits

• Rimdevice Compatibility: Pairs with rim-type exit devices in the Hager 4500 Series (such as the Hager 4501), enabling two single-door devices on a pair of doors — no vertical-rod hardware required.
• Full-Opening Clearance on Demand: The non-keyed removable design uses an internal release mechanism so authorized personnel can pull the mullion to clear the full opening width for furniture, equipment moves, or deliveries, then reinstall it quickly.
• Heavy-Gauge Tube Steel Construction: Built for institutional and commercial-grade durability, the 4900 installs into head and sill strike preps for a secure, rigid mount.
• Simplified Maintenance: By enabling the use of rim exit devices instead of vertical-rod hardware, the 4900 reduces the number of moving parts in the opening and simplifies future service and inspection.
• USP Prime for Paint (BHMA 600): The factory-primed steel finish accepts field-applied paint, making it straightforward to match any door or frame color on the jobsite.
• HagerOnHand Express — Quick Ship: This mullion set is stocked in Hager's HagerOnHand Express program and typically ships within 1–2 business days.

The Hager 4900 removable mullion is well-suited for a wide range of commercial and institutional double-door openings, including:
