Industrial Wallmount Rack 12U

The Tripp Lite SRN3RG12USDP is a sealed steel enclosure that holds 12U of rack-mount equipment up to 32 inches deep. Its NEMA 3R rating shields installed hardware from rain, sleet and snow in outdoor or wash-down environments. Lockable doors and a 200 lb weight capacity add physical security for remote sites.

Upgrade From Open Frame Racks

This enclosure replaces open wall racks when moisture, dust or tampering risk rules them out. The jump is worth it for installations that must stay online through weather events or in unsupervised locations. Integrated fans with a thermal switch automate cooling without extra wiring.

Suits Edge And Outdoor Deployments

Network closets, traffic cabinets and industrial floors benefit from the hinged swing-away design that grants rear access in tight corridors. Buyers who need deeper than 32 inches or a higher load rating should look at floor-standing alternatives. The 225 lb unit weight demands solid mounting structure.

Questions about this item

What wall space and mounting surface are needed for the 27.17 in high, 29.17 in wide, 39.17 in deep enclosure that weighs 225 lb?

The unit requires a wall area at least 27.17 in high by 29.17 in wide with 39.17 in of clearance from the wall; the mounting surface must support 225 lb plus up to 200 lb of equipment.

How do the internal fans operate and what setting is commonly overlooked?

The internal fans are controlled by a thermal switch that turns them on automatically when the internal temperature rises; the step often missed is verifying that the switch is enabled after installation.

What ongoing maintenance does the NEMA 3R sealed enclosure need?

The sealed NEMA 3R housing protects against rain, sleet and snow, so maintenance is limited to periodically cleaning the fan intake vents and checking that the door seals remain intact.
