Designed to maximize space without compromising protection, the Tripp Lite SmartRack Industrial Enclosure is the rugged solution for housing rack-mount equipment in tight or high-traffic environments. This NEMA 3R-rated, wall-mount enclosure is crafted from steel and finished in a bold red powder coating, delivering dependable security, durability, and organization for critical network infrastructure and industrial gear. With a 12U capacity for 19-inch rack-mount equipment, it provides ample room for network switches, patch panels, small servers, and related components while keeping cables neatly managed and accessible. The combination of a hinged back, a lockable front, and a built-in cooling fan with a thermal switch ensures equipment operates within safe temperature ranges, even in demanding settings.

  • Space-saving wall-mount design for 12U of 19-inch rack equipment: This compact enclosure is engineered to fit in confined spaces and concentrate essential networking hardware where it’s most needed. Its 12U rack capacity supports a wide range of devices, including network switches, patch panels, small servers, and other 19-inch equipment, enabling clean, organized, and scalable configurations in data closets, maintenance rooms, or industrial environments.
  • Rugged steel construction with red powder-coated finish: Built to endure demanding environments, the SRN3RR12US uses heavy-gauge steel for structural integrity andShielding against impacts, dust, and contaminants. The red powder-coated exterior not only adds visibility and branding but also provides corrosion resistance, helping equipment stay protected in both indoor and outdoor-adjacent zones.
  • NEMA 3R rating for reliable protection in harsh environments: With a NEMA 3R designation, this enclosure is designed to resist rain, sleet, and snow, as well as dirt and windblown debris. It’s an ideal choice for spaces that require weather-resistant enclosure protection, including exterior walls, loading docks, and partially sheltered outdoor areas where equipment housing must remain secure and interior components protected.
  • Hinged back with a locking front door for easy cable management: The hinged back panel allows convenient rear access for cabling, power distribution, and equipment installation, while the locking front door provides secure access control. This combination simplifies cable routing, testing, and future upgrades, helping technicians maintain a tidy, serviceable rack while maintaining security.
  • Integrated cooling with a fan and thermal switch for safe operation: Equipment often generates heat, and proper airflow is essential to avoid performance degradation or component failure. The enclosure includes a fan with a thermal switch to regulate internal temperature, delivering efficient cooling with quieter operation and extending the life of installed devices even in busy network closets or shop floors.

how to install Tripp Lite by Eaton SmartRack Industrial Enclosure

Step 1 — Choose a secure, stud-backed wall location: Select a solid wall area with enough clearance to accommodate the 28 in. depth and a minimum of airflow around the enclosure. Confirm the location supports the combined weight of the empty enclosure plus installed equipment. Use a level to mark anchor points that align with the enclosure’s mounting holes.

Step 2 — Mount the enclosure to the wall: Drill pilot holes and install appropriate wall anchors or lag screws suited to the wall material (concrete, masonry, or wood studs). Lift the enclosure into place and secure it firmly with the supplied mounting hardware, ensuring the unit sits level and securely attached to the wall to withstand equipment loads and potential impacts.

Step 3 — Route cables and plan rear wiring: Open the hinged back for easy access and arrange cable runs to minimize cable strain. Plan for adequate space behind the equipment to ensure ventilation, simplify future expansion, and maintain organized routing for power, data, and any management accessories.

Step 4 — Install 19-inch rack-mount equipment: Slide in the rack-mount devices, aligning them with the vertical rails. Secure each device using standard cage nuts and screws, mindful of weight distribution to maintain balance and stability. Take advantage of the 23-inch recommended maximum depth for equipment to ensure proper fit and ventilation without crowding.

Step 5 — Close, lock, and test: After cabling is complete, route final patches and power connections, then close the front door and engage the locking mechanism. Power on equipment and verify that cooling fans engage appropriately with temperature changes, fans run quietly, and there is no abnormal heat build-up in the enclosure. Conduct a quick functional test of connected devices to confirm proper operation and cable integrity.

Step 6 — Maintenance and accessibility: Establish routine checks for door locks, seals, and cable management. Periodically inspect for dust buildup, verify that the cooling system responds to temperature shifts, and confirm that the enclosure maintains a clean interior for long-term reliability.

Indestructible ball….Destroyed my dog’s goals
Color: Brown
I have a golden retriever that would rather watch the world burn with every toy I’ve ever gotten him than play nice with any of them. He burns through toys faster than a cardboard bonfire. However, the trap was set…I bought this as a last ditch effort to show that four legged champion of destruction that he could be bested… I remember it to this day.. It was a Tuesday - raining The ball came in the mail and as I nervously unwrapped and opened it, it was as if he knew a new challenger stepped in the ring as he came barreling towards the front door where I stood. Not today I told myself as I stood with confidence with this ball of justice in front of me. The usual sit and stay kept him at bay until I tossed it to him in which he had turned into a frantic honey badger shaking the ball and chewing ferociously he wanted the squeaking thing inside that doesn’t squeak but sounds like an ugly cry. However, it is next Tuesday and the ball stands victorious My dog has been bested and now understands the chain of command. He respects the ball but will always come back for more until he feels that he has won All in all absolutely buy this for aggressive chews and toy playing dogs.

Broke the first day
I purchased the owl ball because of other dog chew toys I purchased from Amazon. Those other chew toys are still holding together. The main reason I got the owl ball is due to the different noises it makes other than the regular squeak noise. After giving the toy to my dog he loved it right away. He especially liked the noise it made. After a few hours, I noticed he was chewing a white tube-like device. I took this away from him and determined it was the noise maker in the owl ball. I examined the owl ball and noticed the glue used to keep the ball cap shut did not hold. On closer inspection, I noticed what looked like rubber cement was used to hold the cap on but if it was rubber cement it was used improperly. Anyway, I just reglued the cap correctly and now it's just a ball because my dog destroyed the noise maker. OK, Since I posted this review I was contacted by the seller. They offered to give me a full refund for the owl ball. I accepted the offer. So, I will try it again, but buy a different color owl this time. I never expected a refund since it's just a ball now, my dog still plays with it and it is holding up very well. The material it is made from is pretty sturdy.

Squeaker not working!
Color: Yellow
I'll give it 3 stars because I love the design and it's sturdy and great for dogs to hold/launch. That said, the squeaker doesn't really work... I tried everything but it just doesn't make any sound. My dog wasn't really interested but when it did make a slight sound he approached it. Once it stopped he lost interest. But he's very difficult to please😆 so if you have a normal dog, he'll probably like it! I hope the manufacturer fixes the squeaker issue because apparently many people are having the same issue, which is a shame because the product is clearly well made! I'm on the fence about returning it just because the quality it's amazing(squeaker issue aside)!

Sturdy rubber ball. Noise maker could be improved
Color: Red
I would have given it five stars because of how much, my dog loved it in the beginning. And shut us up holds true as a sturdy rubber ball. My only complaint is at with one of my dogs being a heavy chewer, she was able to bust the noise making part. The ball never broke open or anything. It just no longer makes noise. You can hear the piece rattling on the inside. The ball itself is still solid tho
