Middle Atlantic Side Panels 37 RU 31-32IN D Racks Solid Steel Panels with Recessed - SPN-37-312

Middle Atlantic SPN-37-312 Rack Side Panels for 37RU, 31-32in Deep Racks

Overview

The Middle Atlantic SPN-37-312 is a pair of solid steel side panels engineered for 37-rack-unit enclosures with depths between 31 and 32 inches. At 64.75 inches tall and 57 lbs, these panels are purpose-built for professional AV, security, and IT installations where the rack chassis needs to be fully enclosed — whether you're locking down a telecom room, a head-end closet, or a surveillance head-end in a commercial facility. The recessed lift handles and lift-on/lift-off design mean a single technician can pull and replace panels during cable management or maintenance without fighting fasteners. These panels fit directly into Middle Atlantic's WRK, MRK, VMRK, and VRK series rack families, so if you're already running that platform, compatibility is a non-issue. For anyone building out a Middle Atlantic rack system, the SPN-37-312 closes the chassis properly rather than leaving the sides open to dust and accidental contact.

Key Features

• Solid Steel Construction: Heavy-gauge steel at 57 lbs per panel set means these are structural, not decorative — they won't flex inward against equipment and provide a rigid enclosure wall that holds up through repeated maintenance cycles in busy equipment rooms.
• 37 RU Height / 64.75 in Tall: Matched exactly to 37-rack-unit frames, these panels run the full height of the rack so there are no gaps at the top or bottom. That matters for facilities with dust concerns or anywhere you're trying to maintain consistent airflow management.
• 31-32 Inch Depth Compatibility: Sized for the 31-to-32-inch depth range common in Middle Atlantic's deeper rack configurations — the kind used when you need to house full-depth servers, large NVRs, or oversized power distribution units alongside AV gear. Check your rack's listed depth spec before ordering; panels cut for this depth range won't fit shallower 24- or 28-inch frames.
• Recessed Lift Handles: The handles sit flush with the panel surface, which means they won't snag cables running along the outside of the rack or catch on adjacent equipment in tight equipment rooms. Useful detail when you're dealing with congested rack rows.
• Lift-On/Lift-Off Design: No tools required to seat or remove the panels. This is a practical time-saver during initial installation and during any maintenance window where you need lateral access — pull the panel, do the work, drop it back in.
• Optional Key Lock: The panels support an optional key lock (not included in base configuration), which lets you secure the side access on deployments where physical intrusion is a concern — server rooms, public-access kiosks, or education environments where the rack lives in a semi-public space.
• Black Powdercoat Finish: A durable powdercoat finish resists scratching during installation and looks consistent across the Middle Atlantic rack line. Not a cosmetic-only spec — powdercoat also adds a layer of corrosion resistance in environments with fluctuating humidity.
• Beveled Corners: Beveled edges reduce the risk of cuts and snags during panel handling — a minor but real benefit when two technicians are maneuvering 57 lbs of steel panel into position in a tight room.

Integration & Compatibility

The SPN-37-312 is designed specifically for the Middle Atlantic WRK, MRK, VMRK, and VRK rack series at the 37 RU height and 31-to-32-inch depth configuration. If you're specifying a new rack build or expanding an existing rack accessories installation, verify your rack model number maps to one of those series and that the depth falls within the 31-32 inch range. Middle Atlantic's naming convention encodes depth in the rack model SKU — cross-reference your rack's spec sheet if there's any ambiguity. These panels are not interchangeable with other rack brands or with Middle Atlantic racks outside this depth range. For integrators managing multi-rack rows, the consistent lift-on/lift-off design across the panel line means the same removal technique applies to every enclosure in the row, which simplifies crew training on larger deployments. Pair with compatible rack enclosure components — top panels, doors, and casters — to build a fully enclosed Middle Atlantic system. If you're planning a large rack infrastructure project, reviewing a rack planning guide before finalizing depth and height configurations can prevent compatibility mismatches on delivery.

Frequently Asked Questions

Q: What rack series is the SPN-37-312 compatible with?

A: The SPN-37-312 is compatible with Middle Atlantic WRK, MRK, VMRK, and VRK series racks configured at 37 RU height and 31-32 inches of depth. It is not designed for other rack brands or Middle Atlantic racks outside this depth range.

Q: Do the panels include a key lock?

A: The base SPN-37-312 configuration does not include a key lock. The panels are designed to accept an optional key lock as an add-on for deployments requiring secured side access.

Q: How are the panels installed — do I need tools?

A: The SPN-37-312 uses a lift-on/lift-off design, so no tools are required to seat or remove the panels. The recessed lift handles allow a technician to position and pull panels without additional hardware.

Q: How heavy are the SPN-37-312 panels?

A: The panel set weighs 57 lbs. Plan for two-person handling during initial installation given the 64.75-inch height and steel construction.

Q: What is the height of the SPN-37-312?

A: The SPN-37-312 panels measure 64.75 inches in height, sized to match a 37-rack-unit frame top to bottom.

Q: Can the SPN-37-312 be used with racks that are 28 inches deep?

A: No. The SPN-37-312 is cut for 31-32 inch depth racks. Using these panels on a shallower rack frame will result in a poor fit. Middle Atlantic offers separate panel SKUs for other depth configurations.

Marty Allison

The SPN-37-312 is the panel set I spec when a client has a 37 RU Middle Atlantic WRK or VRK rack in a space where the sides can't be left open — whether that's because of dust, physical security policy, or just a clean installation standard. At 57 lbs for the set and 64.75 inches tall, these are not lightweight trim pieces; they're a structural closing element that finishes the enclosure properly.

Technical Highlights:

• Lift-On/Lift-Off Design: No fasteners means a single technician can pull a panel in under a minute during a maintenance window — important when you're billing by the hour and the rack is in a live head-end room.
• 31-32in Depth Range: This depth spec is the critical ordering variable. Middle Atlantic builds panels for specific depth bands, and a mismatch means the panel won't seat correctly. Confirm your rack's listed depth from the original purchase order before specifying the SPN-37-312.
• Optional Key Lock Provision: The panel accepts a key lock accessory without modification, which lets you add physical access control to the rack sides post-installation if security requirements change — useful for phased builds where the security posture gets tightened after initial deployment.

Deployment Considerations:

• At 57 lbs and 64.75 inches, two-person handling is practical for initial installation — particularly when working in a finished equipment room where you can't lay the panel flat to maneuver it.
• The SPN-37-312 covers WRK, MRK, VMRK, and VRK series only — if your project mixes rack series from different Middle Atlantic families or uses a non-Middle Atlantic frame, these panels won't fit. Verify series and depth before the panels ship to the job site.

This is the right panel for a 37 RU Middle Atlantic rack in a corporate security operations center, a building automation head-end, or a surveillance equipment room where the rack needs to be fully enclosed and accessible by maintenance staff without tools — but lockable when the room is unattended.
