Arm Type Details
The dead stop parallel arm mounts the closer to the push side of the door, keeping the arm assembly close to the door for a low-profile, tamper-resistant installation. The integrated dead stop feature limits the door's opening arc, stopping it at a predetermined angle to prevent contact with walls or other obstructions while still delivering smooth, controlled closing.
