Krieger recommends only certain coordinators for gaining maximum performance from your sound control pair doors. Due to the Cam Lift hinge assemblies requirements Krieger recommends the following manufacturers and models coordinators:

TRIMCO: 3092

ABH: 3780

Note 1: All UL rated sound control doors will require a coordinator to be UL certified.

Note 2: The coordinators listed above are not compatible on acoustical pairs with dual-astragals for openings with leaves exceeding 46" in width. Acoustical pairs with leaves exceeding 46" widths (Frame openings > 92") must utilize a mullion. Please contact factory for details.
