-

Operator, straight arm, and installation hardware: Not included unless specifically stated
This arm should be selected by operator model, rail arrangement, door construction, and existing linkage—not by appearance alone. Verify the operator identification label and compare the original arm dimensions and mounting holes before ordering.
Inspect the straight arm, door bracket, trolley, clevis pins, retaining hardware, and mounting structure during replacement. Worn or incorrectly positioned linkage can affect door travel and operator limits.
Disconnect and lock out operator power before service. Secure the door independently and have the arm installed and adjusted by a qualified commercial door technician.
