Hammond, HWM Series, Heavy Duty Swing-Out Wall Mount Cabinet Vented 20U 31D

The Hammond Wall Mount (HWM) cabinet

Designed with the technical professional in mind. Our modern design enables the cabinet to be installed in less time and using fewer installers than similar cabinets of its size. Fabricated from heavy duty steel, the HWM is available in up to 32U, 31.7” overall depth and can support up to 350 lbs of equipment. The HWM is guaranteed not to drop down when the center section is opened. Similar products from other suppliers can drop down when the center section is opened which can result in costly equipment failures due damages to storage devices. The HWM design prevents the center section from dropping saving you time and money from equipment replacement.

The vented front door and side panels were specifically designed for high capacity servers, switches and power management devices. Optional locking solid doors are available for all sizes.
