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.

An Actual Nice Chair for a Decent Price. +2 for the Tool.
Color: Black Grey
Welp, My old chair finally broke, so It was time for a new one. I ended up coming across this chair here, and I couldn't really find anyone talking about it online. I decided to give it a shot since it was on a good sale for Christmas, going down to 99$. I'm going to be honest, I am pleasantly surprised. The cushioning for it is a little firm, but that is perfect for me. Its pretty average when it comes to office chairs, but having the added lower back support is a great touch. I have no complaints about it. The one thing that I am actually really happy about isn't on the chair. Don't get me wrong, over the week I have been using it, It has been nothing but great. That thing is the actual tool it came with. Its a basic Allen key, but the top of it is a molded handle instead of a "L" piece of metal. It made the already easy process of putting together this chair even better. Even after this chair has ran its course like all other chairs, I'm going to still use this tool. So yeah, I think 5 - stars pretty accurately describes how I feel about my chair.

Comfortable chair that works great for long hours
Color: Black
I’ve been using this office chair for a few days and it’s been very comfortable for working and longer desk sessions. The high back design and ergonomic support help maintain good posture, while the cushioning stays comfortable throughout the day. The chair feels sturdy and stable, and the 330 lb capacity gives it a solid, durable feel. It also rolls smoothly and quietly, which is nice when moving around the workspace without creating a lot of noise. Overall, it was easy to assemble, looks professional, and offers great value for the money.

Very Comfortable Ergonomic Chair - Great for Long Work Days!
Color: Black, Color: Black
I’ve been using this ergonomic office chair for a couple of weeks now and I’m genuinely impressed. For the price, it offers excellent comfort and support. What I like: • Very comfortable padded seat and backrest — I can sit for 8+ hours without back pain. • Good lumbar support and adjustable height/armrests. • Holds up to 330 lbs easily (I’m 240 lbs and it feels very stable). • Smooth rolling wheels and sturdy base. • Easy to assemble (took about 20 minutes). The mesh back breathes well and doesn’t get hot. It looks professional in my home office too. Overall, this is a solid ergonomic chair. If you spend a lot of time at a desk, I highly recommend it. Would I buy it again? Yes, definitely.

Great if you're average height.
Color: Black
Comfortable for the price. The seat could be a bit better, but for a budget friendly ergonomic chair, it's well made and has helped a lot with my back pain caused by my previous desk chair. Assembly wasn't terribly difficult, though I did have one screw with damaged threads. Luckily they ship spare screws in the kit, so that was a non-issue. Rollers work great on my small rug and hard flooring and don't tend to tangle cords or cables too much. Size wise, works great for my frame (5 ft 6 in) but for someone more than a few inches taller than myself, you should probably look at another chair.

Great chair
Color: Black
I am very happy with my purchase. Easy to assemble but be aware your drill bits included with your set won't fit their screws. However, you can get a fair bit done with the drill and then use tool included to adjust. Super comfortable and exactly the right height for my desk. Highly recommend for quality exceeding price point.
