The Middle Atlantic MRK Series 44RU Pre-Configured Rack delivers a purpose-built solution for professional AV, IT, and broadcast deployments. Engineered to a precise standard, this rack maximizes space, simplifies installation, and keeps gear organized with industry-leading cable management and accessibility. With a 44 rack unit (RU) capacity housed in a compact 21-inch-wide, 31-inch-deep footprint, it’s ideal for control rooms, studios, classrooms, rental fleets, and data/AV closets where reliability and repeatable performance matter. The MRK pre-configured design means you can deploy with confidence, knowing a robust, rack-ready enclosure is ready to accept your equipment, power distribution, and cooling accessories without the usual on-site customization delays.
- Optimized 44RU capacity in a compact footprint. The MRK Series stores a wide range of standard 19-inch equipment while maintaining accessible front and rear gear, streamlined cable pathways, and efficient airflow. This balance of density and serviceability makes it suitable for dense server racks, AV matrices, audio consoles, video processors, and network gear.
- Pre-configured for rapid deployment and repeatable setups. This rack arrives with factory-installed rails and essential cable-management provisions, so technicians can proceed with device installation, cabling, and testing without the customary rail fabrication or partial builds. It’s a dependable choice for multi-room installations, broadcast suites, and rental inventories where consistency is key.
- Durable, professional-grade construction you can trust. Built from robust steel with a protective powder-coated finish, MRK racks withstand the rigors of daily use, frequent openings, and long-term equipment loads. The rugged frame and finish project a professional appearance in any install environment—from executive rooms to production studios—while maintaining structural integrity over time.
- Comprehensive cable management and airflow considerations. Thoughtful internal organization supports neat cable routing, rear access for easy maintenance, and planning room for cable harnesses, power distribution, and cooling accessories. When cables are orderly, signal integrity improves and service calls become fewer and faster.
- Versatile compatibility for a wide range of deployments. The MRK Series is designed to accommodate AV, IT, broadcast, education, and enterprise applications. It integrates with a broad ecosystem of mounting rails, PDUs, cooling options, and accessories, enabling scalable, modular configurations that adapt to evolving gear needs.

A daily digestive game changer
Size: 1.46 Pound (Pack of 1)
I’m an 81 year old male having problems with my stomach. My Gastroenterologist after numerous tests including a colonoscopy, recommended Meta Mucil, to my surprise. I was expecting more prescription meds. I have been using it every day and I understand why this is what he recommended for me. I feel better already having only used Meta Mucil for a little over a week. It is an excellent product but speak to your doctor first if you are having digestive problems. I also like the fact that it’s sugar free.

Spicy little organizer
Size: 7.4" - 3 Drawers (2.2" each drawer), Color: Black, Size: 7.4" - 3 Drawers (2.2" each drawer), Color: Black
I just love being able to organize a cupboard and make it neater and more efficient. This spice rack is just the ticket to help me do just that. The rack is very well made. The drawers slide out easily and are very sturdy. It was so easy to install - there was really no assembly required. It holds 30 of the average sized spice jars.
Not only is it very functional, but it looks really good, too. Finding my spices will be much easier now.
I would buy this product again. It was a really great price and a very good quality.

Great product & strong tape! Just check the width if ALL of your spices will fit first :)
Size: 7.4" - 3 Drawers (2.2" each drawer), Color: Black
It's great! I didn't have to put it together, it was already assembled. Organized my spices in the cabinet making it look way more neat and easier for me to access ALL my spices. It comes with the two-sided sticky tape that helps it stay in place. Only two things I would say is be careful when placing the rack with the tape down and wanting to pull it back up to rearrange or move it, the tape is really strong, and check the width of the organizer of where you place your spices because I didn't see if there were wider width options for my bigger spice bottles. Other than that, still love it :)

Good racks, 2 slides instead of 1, smooth action
Size: 7.1" - 2 Drawers (3.3" each drawer), Color: Black, Size: 7.1" - 2 Drawers (3.3" each drawer), Color: Black
Pros: 2 sliders instead of just one, smooth action on the slides, slides ‘lock’ into place when retracted
Cons: none for me, other than no option for a single drawer in this size
Needed a wide 2-tier rack to go along with other racks I bought at the same time.
I chose this one primarily because:
- it has 2 sliders, instead of a single one in the middle.
- it’s shorter than others I looked at and I needed to fit some taller items.
- there’s only screws attaching the sliders to the base, which I was going to remove to reduce height.
I really only needed a single 2-tier rack in this size, but it was only offered as a double. Fortunately, the sliders were only affixed to the base with screws and not rivets, so dismantling a single drawer was easy and didn’t require doing any damage.
If you happen to need to do the same, but still have to use the base to clear a lip at the bottom of the cabinet, the metal of the base should be easy to cut in half if you have or have access to the power tools to do so. If you don’t, you could still dismantle 1 rack and just create a new base with some thin wood, then screw both directly to the cabinet.
No complaints, would buy again if it were offered in a single-drawer configuration. Having 2 slides was still definitely a big plus, nonetheless, but I now have half a unit that I don’t necessarily need.
I would note that the sliders don't extend quite as far out as I thought they may, but it's really only ≤1" that I'm talking about and they still extend far enough to vertically pull the rear-most item out, so it's not a biggie, just worth noting.
* I didn’t use the adhesive strip and just threw it away, as I intended to secure it with screws from the beginning. If you’ll be using the base, I’d suggest drilling holes through the base and securing it to the cabinet with screws. The adhesive could well be fine, but it’s asking for trouble to have this loaded with glass and have the adhesive give out. No doubt it would happen when you have 3 things on the stove, the phone is ringing and it was the also week you kinked your back something awful, right?

Excellent quality / size.
Size: 7.4" - 3 Drawers (2.2" each drawer), Color: Black
You magnificent SOB! This is an excellent product - it is exactly as advertised, saves space, is well-built and the measurements are spot-on. There is no assembly and the double-sided tape works perfectly to stabilize the unit. Great product and worth the price.
