Single-controller rack mounts hold one compatible controller in a 1U equipment-rack space, while dual-controller rack mounts hold two compatible controllers in the same 1U space. Both use a faceplate and rear cable-management loops, but installers should select the mount designed for the specific controller type and quantity.

When comparing 1U rack mounts for automation controllers, review controller compatibility, single- or dual-device capacity, faceplate design, retention features, and whether the mount accommodates attached rubber feet. Also consider cable-management loops, front- or rear-facing installation options, rack-or-shelf flexibility, and whether rack screws are included.

Rack mounts position one or two controllers in a dedicated 1U space, helping create a neat, consistent equipment rack layout. Integrated retention bars, faceplates, and rear cable-management loops help secure the controllers, manage connected cables, and maintain access to the rack.

Some rack mounts support front- or rear-facing installation, depending on the equipment and mount design. Models with repositionable rack ears can place the equipment at the front or rear of the rack, while controller shelves with fixed faceplates are intended for front-facing installation.
