Door Coordinators

Door coordinators sequence the closing of paired doors so the inactive leaf closes before the active leaf. This collection includes gravity-arm and frame-mounted coordinators, mounting brackets, carry bars, filler or related components used with paired commercial openings and selected fire-door assemblies.

Compare door and frame configuration, coordinator length, active and inactive leaf arrangement, mounting method, required brackets or carry bars, compatibility with exit devices or other hardware, finish, and any fire-rating or project requirements. Coordinator hardware should be selected as part of the complete paired-door opening.

Choosing Door Coordinators

Door coordinators are used on paired openings where the two leaves must close in a controlled sequence. The coordinator holds or delays the active leaf so the inactive leaf can close first, allowing astragals, latching hardware, or other paired-door components to align correctly. The collection includes complete coordinators, gravity arms, mounting brackets, carry bars, and related accessories.

Begin with the door and frame arrangement. Identify the active and inactive leaves, door widths, frame dimensions, coordinator mounting location, and the relationship to closers, exit devices, vertical rods, astragals, and other hardware. Coordinator length and accessory requirements vary, so a unit should not be selected by door width alone.

Mounting brackets and carry bars can be necessary when the frame, door construction, or hardware projection changes how the coordinator operates. Some brackets are intended for particular exit-device or soffit-latch conditions. Match these parts to the coordinator and opening details rather than treating them as universal accessories.

Paired fire doors can have specific sequencing and listing requirements. When the opening is fire-rated, confirm that the coordinator, mounting accessories, closers, latching hardware, and complete assembly meet the applicable requirements. Product descriptions that mention fire rating should be verified for the exact model and installation condition.

For replacement projects, identify the existing coordinator model, length, mounting brackets, and related door hardware before removal. Matching the current preparation and operating sequence can reduce unnecessary modifications and helps preserve reliable paired-door operation.
