Industrial wall-mount rack

This Tripp Lite SmartRack enclosure provides 12U of secured mounting space for servers and network gear in industrial or outdoor settings. The NEMA 3R rated steel housing protects equipment from rain, sleet and snow while the lockable door prevents unauthorised access. It suits installers who need a rugged cabinet that can be mounted directly to a wall or structure.

Thermal management and access

Internal fans operated by a thermal switch draw air through the sealed enclosure to keep installed equipment cool during normal operation. The cabinet swings away from the wall on a hinge, giving technicians full rear access for cabling and maintenance without removing the unit from the wall. Power draw is limited to the fan assembly only.

Maximum equipment depth

The enclosure accommodates rack-mounted devices up to 28 inches deep, which is the critical dimension for selecting compatible servers, switches or UPS units. Equipment exceeding this depth will not fit behind the closed door. The overall unit measures 28.5 inches high, 25.2 inches wide and 32.1 inches deep, weighing 146.44 lb.

Questions about this item

How do I mount the 12U enclosure to the wall, and what step is most often missed?

Secure the steel cabinet to structural studs using the full depth of 32.1 in. The step people skip is verifying the wall can support 146.44 lb before drilling.

What maintenance will the internal fans and door seals need over time?

Clean the fan intakes and thermal switch contacts periodically, and inspect the NEMA 3R gasket on the door for cracks to maintain rain and snow protection.

What limit appears first when the enclosure runs fully loaded in hot weather?

The thermal switch on the internal fans activates to increase airflow once internal temperature rises, preventing equipment from exceeding its safe operating range.
