Functional Details

Arm Type Details

This is a Unitrol arm configuration, which integrates a spring stop and hold-open feature into the closer arm. The design cushions the door at the end of its opening cycle and secures it open, reducing strain on the closer and surrounding hardware while offering convenient hands-free operation.
