Industrial wall-mount enclosure

The Tripp Lite SRN3RY12US is a 12U steel rack cabinet designed for wall mounting in harsh environments. Its yellow NEMA 3R rated housing seals against rain, sleet and snow while protecting installed equipment. Lockable doors secure up to twelve rack units of gear against tampering or theft. Internal fans promote airflow to keep components cool inside the sealed enclosure.

Outdoor and dusty locations

This cabinet suits installers who need to mount network switches, patch panels or servers where moisture or debris would damage standard racks. The swing-away hinge allows rear access for cabling and maintenance without removing the unit from the wall. Buyers who require deeper equipment bays beyond the 23 inch limit should look at larger floor-standing enclosures instead.

Twelve rack units of sealed space

The enclosure accepts equipment up to 23 inches deep across its full 12U height, covering most standard switches and shallow servers. Shipping dimensions are 34.56 by 28 by 36 inches at 200 pounds, so the wall structure must support that load. Equipment deeper than the stated maximum will not fit, and the fixed 12U capacity cannot be expanded.

Questions about this item

What mounting hardware do I need to attach this 12U wall-mount rack to the wall?

The enclosure ships without wall anchors; you must supply lag bolts or concrete anchors rated for the 200 lb shipping weight and the wall material you are mounting to.

Will my existing 20-inch deep patch panels fit inside the 23-inch maximum equipment depth?

Yes, the sealed housing accepts equipment up to 23 in. deep, so standard 20 in. patch panels and switches will fit with room for cable management.

How can I verify the built-in fans are moving air after installation?

Power the fan circuit and feel airflow at the vent openings; the fans should spin continuously when the unit is powered, confirming active cooling.
