Designed to meet the demands of professional installers, the Middle Atlantic MRK Series Rack delivers rock-solid performance in a compact, space-saving package. With 40 rack units of mounting space and a substantial 36-inch depth, this enclosure is built to handle demanding multi-bay projects—from large AV systems and broadcast setups to data centers and network closets. The MRK line is renowned for rugged construction, seismic certification, and a modular approach that makes it a favorite among installing contractors who value reliability, ease of service, and a clean, scalable rack layout. The Cage Nut w/o Rear Door variant provides flexibility for installations that require open-back configurations or that plan to add rear-access options later, while maintaining the sturdy frame and dependable hardware Middle Atlantic is known for. When performance, longevity, and professional aesthetics matter most, MRK stands as a workhorse solution that streamlines workflows and delivers consistent results across complex installations.

  • The MRK Series emphasizes a rugged, space-saving design that maximizes gear capacity without expanding the rack footprint, delivering 40U of mounting space in a single, durable enclosure ideal for crowded rooms and multi-bay configurations.
  • Seismic certification and a high-load rating provide added safety and reliability in environments where movement or vibrations are a concern, making MRK racks suitable for data centers, broadcast facilities, and large control rooms that demand dependable containment.
  • Cage Nut hardware is included for quick, straightforward installation of 19-inch equipment, and this variant ships without a rear door, offering flexibility for open-back setups or for future rear-door additions as site requirements evolve.
  • MRK series compatibility ensures a scalable, modular approach to rack infrastructure, enabling contractors to align multiple bays with consistent dimensions, finishes, and mounting standards for a cohesive, professional facility design.
  • Durable finishes and industry-standard rails support long-term use in demanding environments; a powder-coated steel chassis ensures resistance to wear, while 19-inch EIA-compliant mounting rails maintain precise alignment across equipment brands.

How to install Middle Atlantic MRK Series Rack

  • Plan the location and verify floor load capacity and anchor points to support a 40U, 36" deep rack in your space.
  • Unpack the MRK rack and inspect for shipping damage; confirm that cage nuts and mounting hardware are included as specified.
  • Install the front mounting rails to the rack frame, ensuring they are level and aligned with the 19" equipment spacing standard.
  • Secure rails using the appropriate hardware, then insert cage nuts at the mounting positions that correspond to your equipment’s width and orientation.
  • Begin with the heaviest or deepest devices first, mounting them to the rails with standard 10-32 or manufacturer-recommended fasteners, keeping weight balanced for stability.
  • Route power, data, and control cables through available cable-management features to maintain airflow and access for serviceability.
  • If a rear door is added later, install it according to MRK guidelines and verify that latches operate smoothly and securely.
  • Securely fasten all devices, perform a final cable-management pass, and conduct a functional check to ensure all equipment powers on and operates correctly.
  • Document the rack configuration for maintenance and future expansions, maintaining consistent labeling and organization across all bays.

Frequently asked questions

  • Q: What does 40 RU and 36" depth mean for this MRK rack?

    A: 40 rack units (40U) indicate the total vertical mounting space inside the rack, while 36" depth specifies the distance from the front to the rear of the enclosure. This combination supports a wide range of standard 19-inch equipment and is well-suited for multi-bay installations that require substantial gear capacity without a large footprint.

  • Q: Is the rear door included with this cage nut configuration?

    A: No. This variant is designed as Cage Nut w/o Rear Door, offering open-back flexibility or the option to add a rear door later if needed for additional security or airflow control.

  • Q: Is the MRK rack seismic-certified?

    A: Yes. MRK series enclosures are seismic-certified, making them a reliable choice for installations in regions where movement or vibration is a concern, and suitable for large, multi-bay projects.

  • Q: What equipment fits in this rack?

    A: The rack is designed for standard 19-inch equipment that fits within 40U of mounting space. This includes servers, patch panels, AV processors, network gear, power distribution, and other rack-mountable devices commonly used in data centers, broadcast facilities, and control rooms.

  • Q: How should I approach installation to ensure long-term performance?

    A: Start with careful planning of equipment order and weight distribution, install rails and cage nuts correctly, route cables to minimize tangling and airflow obstructions, and consider adding rear-door options or additional cable-management accessories as needed to maintain a clean, scalable rack system.

  • Q: Can I customize the MRK rack for specific site requirements?

    A: Yes. The MRK series is designed for modular, scalable installations. You can tailor rear-door configurations, add cable-management accessories, and align multiple bays for a uniform, professional look across large facilities.

Perfect for ball demolishers
Size: Medium
The dogs love the chuck it brand. I don’t know what it’s made of but they go crazy over them. Will not play with another ball. Wonder if it’s “laced” with an addictive scent. Have pits. Very durable. Not able to chew to pieces. Last for about 6 months before there is a small break. I keep a back up because when the ball goes missing the house is in chaos. 😆 🤪

Chuckit medium rebound balls
Size: Medium
My 8 month old German shepherd dog loves these balls. They are easy to throw, they bounce great, they are very chewable! She keeps one in her mouth most of the time. It satisfies her need to chew and she does not chew other things. She drops it in the water and lets the hole fill up and drinks that way. The only problem that has caused is suction in her mouth and difficulty in dislodging it for her. However, she would be lost without it!

These are definitely indestructible
Size: Medium
Both of my dogs can destroy a ball in a matter of minutes if I let them play with them (supervised) as is. Well not with these balls. They are the ONLY ones I have found that are 100% indestructible. Please only let your dogs play with these as a toy when supervised though. They go really far when throwing them, so both dogs get a good amount of running and exercise with these. I also bought these because they have the hole in the middle of the ball which is very important in the event that a dog gets one stuck at the back of their throat. This allows them to breath unlike those without this hold. It's an unlikely event, but as dog owners, we all need to be aware of this and educate ourselves on what to do if this SHOULD happen. This isn't a scare tactic, nor a reflection of this particular brand, it can happen with any type of ball. My two dogs are about 45ish lbs and the size is perfect for them, I don't want anything smaller than this. They love them. There is no annoying squeak. Really easy to wash after use. Some balls take forever to get the slimy saliva off, but these don't.
