Most commercial door closers vary, but most are typically use a heavy-duty metal arm connection that prevents the door from slamming open or close. If your commercial door uses the standard arm mechanism, the steps are as follows:
- Select door opening and mark holes on the commercial door for door closer and holes on frame for arm shoe.
- Drill or tap pilot holes in the door and frame, including screws. Most often, all-purpose screw pilot holes can be made using a drill with the correct bit size, while machine screws require you to tap the hole through.
- Install the arm shoe assembly to the door frame using screws provided with your commercial door closer kit
- Mount the door closer to the door using the screws provided and ensure that your pilot holes alight with the pre-drilled holes in your mount. The speed adjusting arm or hydraulic valve needs to be positioned toward your door's hinge.
- Install the main arm to the top pinion shaft, perpendicular to the door. Make sure you secure the arm with the provided hardware.
- Adjust the forearm length to be perpendicular to the frame when assembled to the preloaded main arm.
- Secure the forearm to the main arm with the provided hardware and secure the pinion cap over the shaft at the bottom of the closer.
