22U Open Frame Server Rack

The iStarUSA WX-228 is a 4-post open frame rack providing 22U of vertical mounting space. It suits server rooms and labs that need accessible equipment installation without enclosed cabinet walls. The frame accepts most standard rackmount chassis up to 29 inches deep. Horizontal rails adjust to match varying equipment widths.

Passive Cooling and Stable Placement

An open frame design eliminates fan noise and power draw by relying on ambient airflow through the 39.75 inch internal height. SPCC steel construction at 2.0 mm for rails and 1.2 mm for the top panel adds rigidity without active components. Locking casters secure the 2200 lb unit on uneven floors while allowing relocation when unlocked.

Optional Panels and Depth Adaptation

Side panels and front or rear doors are sold separately to add physical security or airflow management later. The horizontally adjustable rails accommodate chassis depth variations within the 29 inch limit. Buyers needing deeper server support or integrated cable management channels will need a different rack platform.

Questions about this item

How are the mounting rails adjusted during installation, and which step is often missed?

The horizontal rails slide to match chassis width; the step often missed is tightening all rail screws after alignment so the 22U frame stays square under load.

What maintenance will the casters need over time?

The locking casters should be inspected periodically for debris in the swivel bearings and for brake engagement; clean and lubricate the bearings if rolling resistance increases.

Which limit appears first when the rack is fully populated and running continuously?

The supported chassis depth of 29 inches is the first constraint; equipment deeper than that cannot be mounted regardless of weight capacity.
