How to Repair a Rod Control Lock

Rod Control Lock is a kind of door lock, which is used in large equipment doors. These locks are generally made of zinc alloy, stainless steel and plastic, and can be customized according to the requirements. It can be applied to industrial cabinets, distribution boxes, switchboards, automation equipment and electrical equipments. Some can be equipped with padlocks to strengthen anti-theft requirements.

Problem #1: Rods fall out or are bent

This is usually the result of bushing wear, and can easily be repaired by disconnecting the rods and replacing any worn out bushings. The bushings connect the rods to the locking and latching mechanisms, so it's important that you examine them carefully for any movement or "slop" between them.

Problem #2: The mechanism won't open with the button or key

If you have a mechanical locking and latching mechanism, this is probably a case of bushing wear. Pull the inner and outer handle to see where the rods connect to the latching mechanism, and watch for any movement between them.

This is a very common cause for both mechanical and electronic door lock systems. The rods connecting the handles and actuators are connected to each other, and the controls for locking and unlocking are attached to the door panels. Push and pull on the button or handle to see if any rods are loose from their bushings.
