Tripp Lite SmartRack Side Panel with Key-Locking Latches for 42U Server Rack Cabinet, 1 Panel

The Tripp Lite SR42SIDE is a single side panel designed for SmartRack enclosures that hold 42U of equipment and feature a 42 in. depth. It closes off the side of cabinets such as the SR42UB, SR42UBEXP, and SR42UBWD, giving the rack a finished look while adding a layer of physical security.

The panel is made of heavy-duty steel, so it stands up to bumps, scrapes, and constant activity in data centers and network closets. Two latches come pre-installed and accept the included keys, allowing administrators to lock the cabinet quickly and deter casual tampering or theft.

Because this is a single panel, it is ideal when you need to replace a missing or damaged section or when you want to secure an expansion rack that was originally open on the sides. Using it can also help direct airflow through the intended front-to-back path, which supports more consistent cooling for servers and switches.

Installation is straightforward. Lift the panel into place, engage the spring-loaded latches, and turn the key—no drilling or special tools required. The panel meets RoHS directives and carries Tripp Lite’s five-year limited warranty for added peace of mind.
