• All COR units function easily. The active door lever, located nearest to the active stop, holds the active door open until the trigger mechanism is released by the closing of the inactive leaf.

• All COR units may not function correctly with swingclear hinges.

• All COR units are equipped with an adjustable override feature which allows the active door to close under extreme pressure.

• All COR units are compatible with Flush Bolts.

• The COR Series is available in five sizes for variable door opening widths.

• The COR Series does not cover the entire length of the stop, so a FL filler bar can be provided to maintain architecturally clean lines.

• COR Series Coordinator Channels and FL fillers are made of aluminum.

• Optional Filler Bars: FL20 - 20", FL32 - 32" and FL44 - 44", available to maintain clean line.

• Optional Mounting Brackets available: MB1, MB2, MB1F, MB2F, MB3F, MB1V, MB2V, and MB3V for other stop applied hardware.
