Ives COR7G US3 Door Coordinator 7 Inch Gravity Arm

Product Description

The IVES COR7G US3 is a door coordinator designed to control the closing sequence of paired doors in double-door applications. It ensures the inactive leaf closes before the active leaf, which is required for proper latch bolt and vertical rod device operation. Finished in Bright Brass (US3), this coordinator includes a 7 inch gravity arm that automatically resets after the doors open, eliminating the need for spring tension adjustments. It is installed by commercial door hardware technicians and locksmiths working on paired door assemblies in commercial or institutional settings.

This coordinator is suited for double-door openings where exit devices or latch hardware require the inactive door panel to close first. Typical installations include office buildings, schools, hospitals, and other commercial facilities where paired aluminum, steel, or wood doors are fitted with vertical rod or mortise exit devices. The gravity arm design simplifies field adjustments and reduces maintenance compared to spring-arm alternatives.

Installation Notes

Installation is typically performed by a licensed door hardware technician or locksmith familiar with commercial exit device systems. Ensure all door closers and exit devices are fully depowered or in the hold-open position before mounting hardware. The coordinator must be sized and positioned to the door frame per the manufacturer template; improper placement will prevent correct leaf sequencing. Local building and fire codes, including applicable sections of NFPA 80, may govern coordinator requirements for rated door assemblies.
