Krieger Specialty Products
Krieger recommends using only certain coordinators to ensure maximum performance from your paired acoustical doors.
Please note all UL-rated sound control doors require a coordinator to be UL-certified.
Recommended Coordinators
Due to the Cam Lift Hinge assembly requirements, Krieger recommends the following coordinator manufacturers and models:

TRIMCO: 3092
Rockwood: 1700
ABH: 3780

Coordinators with Oversized Acoustical Doors
The coordinators listed above are not compatible for use with acoustical door pairs that have dual astragals for openings with leaves exceeding 46" in width. Acoustical pairs with leaves exceeding 46" in width (frame openings > 92") must utilize a mullion. Please contact us for more details.
