1/2" Top Rail Application

The 1/2" designation refers to the required top-rail depth of the compatible door.

This side-load arm is commonly used where the commercial aluminum door has a shallow 1/2" top rail and requires an S-type top arm for connection to the overhead concealed closer spindle.

Always verify the existing door rail and arm configuration before ordering.

Side-Load Design

Unlike an end-load arm, the side-load configuration is installed through the side of the compatible door top rail.

This configuration is commonly used on center-hung aluminum entrance doors equipped with overhead concealed closers.

The design allows the installer to adjust the door for proper alignment within the frame.

Adjustable Door Alignment

Compatible S-type side-load arms provide adjustment for:

• Lateral door position

• Door-to-jamb alignment

• Centering within the opening

• Proper operating clearance

These adjustments are especially useful when replacing worn hardware or realigning an existing storefront door.

Designed for Prime 7000 Series OHC Systems

The Prime Door Controls 7000 Series is an overhead concealed closer platform designed for commercial storefront and entrance applications.

The 7000 closer system can be configured with different arm and pivot arrangements depending on the door construction.

Common arm configurations include:

• Side Load Arm

• End Load Arm

• Offset Arm with Track

• Other application-specific OHC arm assemblies

Always match the replacement arm to the original door preparation.
