Designed for professional A/V and data-center environments, the Middle Atlantic MW-CLVRD-40 is a rugged split-vented cabinet door engineered to maximize airflow while preserving a clean, high-end appearance. Crafted from durable steel and finished in a sleek black, this 40RU door is purpose-built to fit MRK, WRK, and VRK rack systems, delivering reliable performance in environments where cooling and accessibility matter. The split vented design, featuring a remarkable 79% open area, enables robust cooling and heat management, helping equipment operate at peak efficiency even under demanding workloads. Whether you’re installing standard audio-visual gear, servers, or patch panels, this door combines professional aesthetics with practical airflow optimization to keep gear cooler, quieter, and easier to service.

  • High open-area vent design: With a 79% open area, the MW-CLVRD-40 provides superior ventilation to promote efficient cooling and reduce hotspots. This generous venting is ideal for racks housing high-density equipment, ensuring air can circulate freely from front to back and across all active components.
  • Split vented cabinet door: The split configuration enables convenient access during maintenance or swapping equipment without compromising overall rack security. The vented sections balance performance and protection, maintaining a professional look while supporting frequent service intervals.
  • Durable steel construction with a black finish: Built to withstand the rigors of installation environments, the door uses rugged steel and a durable black powder-coat finish that resists scratches, corrosion, and grime—keeping racks looking sharp in year-round operation.
  • 3-inch depth for versatile compatibility: Optimized for standard rack depths, this door fits cleanly into MRK, WRK, and VRK assemblies while leaving ample room for cabling strategies, cable management arms, and accessory hardware without crowding the front panel.
  • 40RU capacity and universal rack compatibility: Specifically designed for 40RU installations, the MW-CLVRD-40 is a strong match for mid- to large-scale rack configurations. It’s compatible with Middle Atlantic MRK, WRK, and VRK rack systems, supporting cohesive aesthetics and consistent airflow across the enclosure.

How to install Middle Atlantic 40RU Split Vented Door

  • Prepare and verify: Before installation, confirm that the door is intended for MRK, WRK, or VRK rack systems and that the rack provides 40RU of space. Verify that you have the appropriate mounting hardware and tools for your rack model. Ensure the power to any nearby equipment is shut down if you’re working in an active environment.
  • Remove existing front door or panel: If you are replacing an existing front door, carefully detach it from the rack by loosening mounting screws and setting the door aside. Take note of hinge positions and mounting points to ensure correct alignment for the new door.
  • Align hinges and rails: Position the MW-CLVRD-40 so that its hinge points align with the corresponding rack rails. Check that the vent sections are oriented to maximize front-to-back airflow and that there’s no interference with rack-mounted equipment, cables, or accessory brackets.
  • Secure the door to the rack: Use the appropriate screws or mounting hardware for your MRK, WRK, or VRK enclosure. Start with a few screws on each side to allow fine alignment, then tighten securely, ensuring the door sits flush and operates smoothly without binding against rails or cabling.
  • Test fit and airflow: Close the door and verify that it latches properly and that the door clears adjacent equipment. Open and close the door to confirm smooth operation. After securing, power up any equipment and monitor temperatures to confirm that airflow through the 79% open area remains unobstructed by cables or accessories.

Awesome quality
Color: White, Color: White
Take your time installing! It comes with all the instructions and templates. Make sure you’re screwing this into solid wood. I would not recommend you hang your expensive PC from a particle board table. My Pc fits in well and it’s compatible with a ton of different sizes. Mine has been mounted under my desk for about 6 months and is rock solid. I will say, mine is balancing in there. If I don’t have it at its center of gravity, it could tip out. You can adjust it with the various screw holes but make sure you mount it into something solid.

PC holder that looks great and works on large PCs for easy under desk mounting
Color: Black
After a lot of research and trial and error I finally found the Heavy Duty Under Desk PC Holder. It is the only under desk PC holder that looks good and is able to hold my HP Omen 45L where I want it - under my desk. Putting it together is relatively easy as was the installation to the desk. No messing with cables or round steel tubes to get the job done. The metal is solid, the black powder coating looks great, and the installation hardware is a;l there including a drill bit, hex key, and wrench. You just need to bring a screw driver for the wood screws to attach it to your desk. Read the instructions and make sure you take the depth of your PC into account when attaching the PC holder to your desk, especially if you have a standing desk with motors.

Quality Holder
Color: White
Very quality holder and very sturdy and stable. I purchased it back in April, and it has been holding up nicely. I would definitely say that it is worth the price. I love that it's adjustable, so if I ever decide I want to new PC case, I can still use it (as long as it fits the dimensions of the holder). Putting it together and mounting it was simple. The only reason I'm giving 4 stars is that it did not come with screws, and I had to purchase some. I hope that has been changed since then.
