Middle Atlantic MRK Series 44RU Open Frame Floor Standing Rack — 42" Depth

Engineered to endure the rigors of demanding installations, the Middle Atlantic MRK Series 44RU Open Frame Floor Standing Rack delivers the performance of a workhorse with the flexibility installers need on large, multi-bay projects. This open frame cabinet blends rugged construction with a compact footprint, making it a trusted choice for data centers, pro AV rooms, broadcast suites, and enterprise IT deployments where accessibility and reliability matter most. The MRK series is purpose-built to simplify gear loading, serviceability, and airflow management, so you can deploy, scale, and maintain complex equipment ecosystems with confidence.

Designed for professionals who demand scale without sacrificing ease of use, the MRK 44RU rack prioritizes serviceability and planning versatility. The open frame design provides effortless access to both front and rear panels, making it easier to install, swap, and upgrade components as technology evolves. Its 42" depth accommodates deep equipment such as dense servers, power distribution units, high-performance switches, and large audio/video devices, while still integrating neatly into rooms with limited space. The robust steel frame, reinforced joints, and durable powder-coated finish stand up to years of daily use in environments ranging from broadcast studios to university labs, ensuring that cabling and hardware stay organized and accessible under load. Seismic certification further reinforces its suitability for installations in regions where safety and compliance are paramount, giving installers peace of mind when addressing local codes and project specifications. With 44 rack units of capacity, it offers ample room for a wide array of equipment and accessories, including cable management panels, fan kits, and mounting rails, all while maintaining a clean, professional look that aligns with premium infrastructure standards.

How to install Middle Atlantic MRK Series 44RU Open Frame Rack

Installing the MRK Series rack is a straightforward process that benefits from careful planning and proper hardware. Use this general guide to establish a reliable foundation for your equipment and cooling strategy. Always refer to the official installation manual for precise hardware specifications and safety requirements.

  • Plan placement: Choose a sturdy, level floor with adequate ventilation and access to power, cooling, and network connections. Consider future expansion and the location of doorways, doors, or mounting restrictions in your space.
  • Unpack and inspect: Verify that all components, rails, fasteners, and panels are present and undamaged. Report any shipping damage immediately to avoid delays in deployment.
  • Prepare rails and mounting: Install 19" equipment rails per the manufacturer’s instructions, ensuring proper alignment to support front rack mounting standards and weight distribution.
  • Mount equipment: Begin with heavier devices at the bottom and work upward to maintain stability. Use appropriate screws and hardware compatible with your rails, and leave adequate clearance for cabling and airflow.
  • Cable management: Plan front and rear cable pathways, using cable management panels, ties, and organizers to minimize clutter and maximize cooling efficiency.
  • Airflow and cooling: Position equipment to avoid obstructing vents and fans. Consider adding optional fans, ducting, or blanking panels in unused spaces to promote uniform airflow.
  • Seismic anchoring (if required): In regions with strict seismic codes, anchor the rack to the floor according to local regulations and the MRK series guidelines to ensure stability during events.
  • Final checks: Recheck all connections, tighten fasteners to the recommended torque, ensure front and rear accessibility, and verify that the system can be serviced without removing adjacent equipment.

Simple! Easy! All We Needed!!
Size: Large Triple
These were the only durable rubber like rings that were both the same material; not too thick (not heavy) so my 1 year old Pit, Dixie, was able to latch on to one ring while we grabbed the third ring, leaving enough space so she won't accidentally bite us when grabbing the rings to play. They were also the only ones that came interlocked and cannot be taken apart. She is also a big chewer, which means she can gnaw on these without tearing them apart. The rubber is thick enough to play, but thin enough to twist and flex with her. So far, they are sturdy. She was immediately so excited! Simple and easy!

Great durable dog toy!!
Size: Large Triple
We have a medium-sized dog (45 lb mixed Aussie/Hound) who is a pretty aggressive chewer. He also loves playing tug-of-war with his canine and human siblings using these rings. This is easily his favorite toy. We bought one a little over a year ago that he plays with daily. If finally broke this December just in time to buy a replacement for Christmas! The prior one finally broke when the middle ring came apart at one of the thinner rubber points. He still plays with the intact outer rings as well as his new toy. I wanted to dock this 1/2 star for a few reasons: 1) it is not completely invincible, although I would argue a toy that lasts over a year with pretty constant play for an $11 price tag is a great value. 2) the one we received is not yellow/black. It is blue/green. I was personally thrilled it was blue/green because it ended up being an exact replacement of the one we had previously. However the description does not say "colors vary" and it was hard for me to tell when ordering if I was ordering the correct replacement toy. A clearer description would be appreciated. 3) This is a great toy for one dog, but our other dobbie/cattle dog mix has no interest in them. So not all dogs will love this toy (obviously). 4.5 stars isn't an option so I'm giving this 5 stars because it's just about as close to a perfect dog toy as one can buy (at least for our dog).

Great toy, as long as dog is NOT ALLOWED to chew on it
Size: Large Triple
Let me start by saying that I like this dog toy. My big dog LOVES tugging with it. As long as you keep away when the dog is in a chewing mood, it lasts a long time (my 1st one lasted a year), however, it WILL NOT last if the dog chews on it, as I found out with this one. A friends dog chewed on it while she was behind a snow mound (mostly out of our sight) when it was only a week old. One end ring was barely holding together when we discovered her chewing it. Fortunately it was an end ring, so I still have 2 connected rings for tugging with. It is a great tug toy! But it is also a TERRIBLE chew toy, so make sure to take it away when your dog starts to chew on it and it will give you long service.

Fabulous toy!!
Size: Large Triple
My GSD is always up for a good game of tug-o-war. I purchased these in large and I think I love them as much as my dog. They are super strong and hold up to his 100lb self pulling on one end and my “blah blah-lb” self pulling on the other. (Ha! You thought I would say how much I weigh) I even bought another pair for our cabin so we have some to play with at both places. He isn't a sit and chew on things kind of dog. He gets plenty of playtime and bully sticks for chewing. Not to mention that I wouldn't let him use them as a chew toy anyway. There are toys for play and toys for chew. Therefore, I cant say anything on how they hold up for chewers. So if you let your dog just sit and chew on it instead of giving them something designed for strong chewers, then no it might not hold up to that. All I can say is my German Shepherd is 100lbs with sharp teeth and stronger than me now and honestly he is probably stronger than I have ever been in my life, and they hold up to the pulling and tugging of both of us. Thats what they're designed for and they serve their purpose excellently.

Won't purchase this one again.
Size: Large Triple
J.W. used to make a ring toy such as this, that was softer & thicker with a smaller black ring in the middle, that our dogs all, absolutely loved!!!!! But this one totally bores them to the point none of the dogs will pay it any attention! Please bring back the original 3 ring toy, that J.W. has now changed to just the one ring! I feel like they must have discontinued the toy with the 3 rings they used to sell, with the smaller black ring in the middle? I won't waist my $ on another one of these! Sadly, none of our 3 dogs will play with this specific toy at all! & I generally prefer to purchase J.W. brand toys for our dogs. But this toy doesn't attract them in anyway. It just sits around.
