Middle Atlantic Side Panels 44 RU 26-27IN D Racks Solid Steel Panels with Recessed - SPN-44-267

Middle Atlantic SPN-44-267 44U Solid Steel Side Panels for MRK/WRK Racks

The Middle Atlantic SPN-44-267 delivers a matched pair of full-height solid steel side panels sized for 44U MRK, WRK, and VRK series racks with depths of 26 to 27 inches. At 83 inches tall and finished in black powder coat, these panels close off open rack sides cleanly — a straightforward fit if you're building out a secure equipment room or deploying a freestanding rack in a semi-public space where cable management and physical containment matter. If you're working through Middle Atlantic rack enclosure solutions or specifying a complete rack system, the SPN-44-267 is the factory-matched panel for this depth class.

Key Features

• Solid Steel Construction: Heavy-gauge steel panels (not mesh, not perforated) provide physical containment and reduce airborne dust ingress on the sides of the rack. Appropriate for environments where cable access from the sides is not required and visual screening of rack contents is a priority.
• 83-Inch Full-Height Coverage: At 83 inches, these panels span the full 44U height — no gap at top or bottom. You get consistent coverage whether the rack is sitting on a raised floor or directly on concrete. No partial-height patchwork needed.
• Recessed Lift Handles: Integrated lift handles are recessed into the panel face, eliminating protruding hardware that would snag cables or interfere with adjacent equipment in tight rows. Field installers working in dense rack rows will appreciate not fighting a handle that sticks out.
• Lift On/Off Design: Panels install and remove without tools — lift straight up and off. For environments where panels need to come down for periodic maintenance or cable runs, this saves meaningful time versus bolt-on designs that require a second person or a cordless drill every time.
• Optional Key Lock: The SPN series supports an optional key lock, giving you a tamper-deterrent option for racks in semi-public or shared-access areas — IT closets with multiple tenants, lobbies, or wiring rooms where physical access control to rack contents is a real concern.
• 26–27 Inch Depth Compatibility: Sized specifically for rack enclosure systems in the 26-to-27-inch depth range. Check your MRK, WRK, or VRK rack's depth spec before ordering — Middle Atlantic also offers SPN variants for other depth ranges. Wrong depth = panels that won't hang flush.
• 5/8-Inch Width Addition Per Panel: Each panel adds 5/8 inch to the overall rack footprint. Installing a pair adds 1-1/4 inches total to rack width. Account for this in row-spacing calculations and when racks are placed close to walls or adjacent cabinets.
• Black Powder Coat Finish: Factory powder coat matches the standard Middle Atlantic rack finish. Consistent aesthetics across a multi-rack row without touch-up painting or mismatched colors.
• Sold as a Pair: The SPN-44-267 ships as two full-height panels — left and right — so you're not buying singles and sourcing a mismatched second panel later.

Compatibility and Integration

The SPN-44-267 is part of the Middle Atlantic SPN Side Panel series and is engineered for MRK and WRK series racks with 26–27 inch depth. It also fits VRK series racks in the same depth class. Verify your rack's exact depth before ordering — if your MRK or WRK frame is a different depth (such as 31 or 36 inches), a different SPN variant is required. The SPN-44-267 (often searched as SPN 44 267) will not fit shallower open-frame or two-post racks. For guidance on pairing panels with the right rack accessories for your infrastructure build, confirm the rack model and depth from the rack's label or spec sheet before purchasing.

Frequently Asked Questions

Q: What rack series and depths are compatible with the SPN-44-267?

A: The SPN-44-267 is designed for Middle Atlantic MRK, WRK, and VRK series racks with a depth of 26 to 27 inches. It will not fit racks outside this depth range — check your rack's depth spec before ordering.

Q: Are the SPN-44-267 panels sold individually or as a pair?

A: They ship as a pair — two full-height panels (left and right) covering both sides of the rack.

Q: Do the panels require any tools to install or remove?

A: No. The lift on/off design means panels install and remove without tools — simply lift straight up and off, making periodic maintenance access straightforward.

Q: How much does each panel add to the rack's overall width?

A: Each panel adds 5/8 inch to the rack's width. Installing both panels increases total rack width by 1-1/4 inches — factor this into row spacing and wall clearance calculations.

Q: Is there a locking option available for the SPN-44-267?

A: Yes. An optional key lock is supported by the SPN series, providing a tamper-deterrent option for racks in shared or semi-public access environments.

Q: What is the overall height of the SPN-44-267 panels?

A: Each panel is 83 inches tall, providing full-height coverage for a 44U rack frame with no gaps at the top or bottom.

The SPN-44-267 is a detail that gets overlooked until someone realizes they've got an open-sided 44U rack sitting in a finished equipment room. The lift on/off design is the feature I'd point integrators to first — on a job where you're running cable and revisiting that rack six times over two weeks, not having to break out a screwdriver every time the side panel needs to come down is a real time saver on install day.

Technical Highlights:

• Solid Steel, Full 83-Inch Height: Solid steel at 83 inches means complete side coverage — no open sections, no gaps at the top or bottom rail. For equipment rooms where cable management aesthetics matter to the client, this is the spec that closes the conversation about open rack vs. enclosed.
• 5/8-Inch Width Addition Per Panel: Each panel adds 5/8 inch to rack width — 1-1/4 inches for the pair. That number matters in tight rows or when the rack is being placed close to a wall. Measure twice before committing to your row layout with panels installed.
• Optional Key Lock Support: The SPN series accommodates an optional key lock, which is the spec that makes this panel viable for shared-tenancy IT closets or installs where the rack owner doesn't control all physical access to the space.

Deployment Considerations:

• Confirm your MRK, WRK, or VRK rack is in the 26–27 inch depth class before ordering. Middle Atlantic makes SPN panels for other depths, and the wrong panel simply won't hang correctly on the frame.
• Solid steel panels block all lateral airflow — if your rack is thermally marginal and relying on side convection, installing solid side panels can push temps over threshold. Verify your rack's thermal budget with panels closed before you finish the install.

The SPN-44-267 is the right specification for integrators finishing a 44U MRK or WRK rack in a corporate equipment room, network operations center, or security head-end where the rack needs to look like a finished product — not a construction site — once the project hands off to the client.
