Sargent 644 Double Door Strike for Rim Exit Devices — Black

The Sargent 644 Double Door Strike is a surface-applied strike designed for use on pairs of doors without a center mullion. It provides a reliable latching point for the rim latch of Sargent 8800 Series and 3828 Series rim exit devices, allowing both the active and inactive leaves to function as a coordinated egress pair. The 644 strike mounts to the face of the inactive leaf, eliminating the need for a frame-mounted keeper or center mullion while maintaining positive latch engagement when the active leaf closes.

This accessory is finished in Black to coordinate with matching exit device and trim finishes on the same opening. It is specifically engineered for use with Sargent 80 Series and 2800/3800/8800 Series rim devices on pairs of doors, making it a practical solution for commercial applications where a mullion-free opening is required for accessibility, traffic flow, or aesthetic reasons.

Important Note: The Sargent 644 Double Door Strike is not approved for UL-listed fire door openings. Verify opening requirements before specifying — fire-rated pairs require a compliant, listed strike assembly appropriate for the labeled opening.

About Rim Exit Device Strikes

On a pair of doors equipped with rim exit devices, the active leaf typically carries the rim device that strikes to the frame. The inactive leaf requires its own latching surface for the active leaf's rim latch — that is the role of a double door strike like the Sargent 644. When no mullion is present, the 644 provides a surface-mounted keeper on the inactive leaf face, so the active leaf rim latch positively engages and holds the pair closed until the touchbar is actuated. This configuration supports compliant egress operation and coordinated door-pair security without adding a fixed or removable mullion to the opening.
