21U Wall-Mount Open Frame Rack

This 21U 19-inch open frame rack mounts directly to a wall, providing 21 rack units of vertical space for network switches, servers, patch panels and PDUs. The two-post design uses G-shape rails with square mounting holes that accept the included M6 cage nuts. It suits installers who need a compact, accessible equipment frame in a server room, wiring closet or AV installation.

Adjustable Depth and EIA-310 Compliance

The mounting depth adjusts from 12 to 20 inches, letting you match the chassis length of the equipment you install. The frame meets EIA/ECA-310-E dimensional standards, so rack-mount gear from any compliant manufacturer will align with the hole pattern. The 2.0 mm SPCC cold-rolled steel construction supports a static load of 198.90 lbs while allowing unrestricted airflow around the mounted devices.

Wall Structure and Included Hardware Check

Verify that the mounting surface can carry the rack weight of 36.20 lbs plus the intended equipment load up to the rated capacity. The package supplies 84 M6 cage nuts, 84 M6 screws, 84 plastic washers, 16 M5 assembly screws, 24 M8 bolts and 24 #8 wall-mount fasteners; confirm these match your wall material and stud spacing before starting the installation. Builders who need enclosed sides, lockable doors or a depth beyond 20 inches should consider a different form factor.

Questions about this item

Should I pick the 12 inch or 20 inch depth setting for my equipment?

Choose the depth that matches your deepest device; the rails slide between 12 and 20 inches so you can set them exactly where the hardware sits.

What does the 198.90 lb weight capacity mean once the rack is on the wall?

The 198.90 lb rating is the total load the two-post frame can carry when securely bolted to studs or concrete, covering switches, servers, patch panels and PDUs combined.

How does the EIA/ECA-310-E standard affect what I can mount?

EIA/ECA-310-E guarantees 19 inch wide equipment with square hole spacing will fit the G-shape rails using the included M6 cage nuts and screws.
