Middle Atlantic Pair of Side Panels Fits WMRK-4536 Black Finish ***Drop Ship Only*** - SPN-45-36

Middle Atlantic SPN-45-36 45U Side Panels for WMRK-4536 Rack Enclosures

Overview

The Middle Atlantic SPN-45-36 is a pair of black side panels engineered specifically for the WMRK-4536 server enclosure and compatible WMRK-series racks. At 45 rack units tall and 36 inches deep, these panels deliver a flush, professional finish to open-frame or partially enclosed WMRK installations — closing off lateral access points without requiring custom fabrication. If you're deploying a WMRK-4536 in a data closet, security operations room, or IT room where physical access control and cable management aesthetics matter, the SPN-45-36 is the factory-matched solution rather than an afterthought panel that may not align correctly.

Sold as a pair, the SPN-45-36 covers both sides of the enclosure in a single order — no need to track separate left and right SKUs. The black powder-coat finish matches the WMRK-4536's standard color scheme for a clean, integrated look.

Key Features

• 45 RU Height, 36-Inch Depth: Dimensioned to match the WMRK-4536 exactly — 45U tall and 36 inches deep — so you get a precise, gap-free fit without shimming or modification. If your rack runs shallower than 36 inches, these panels will overhang; verify your enclosure depth before ordering.
• Sold in Pairs: Both left and right panels ship together in a single SKU, simplifying procurement and ensuring you don't end up with a mismatched or single-sided install. One line item covers the full enclosure.
• Recessed Lift Handles: Integrated recessed handles on each panel make installation and removal manageable for a one- or two-person crew. Given the combined shipping weight of 112 lbs, having a second set of hands and using the handles correctly is a practical necessity — not optional.
• Black Finish: Factory black finish matches the standard WMRK-4536 enclosure color, giving AV and IT rooms a consistent rack presentation rather than mismatched panel colors that stand out on camera or during client walkthroughs.
• Compatible with WMRK-Series Racks: Beyond the WMRK-4536, these panels are designed for the broader WMRK rack family — useful if you're standardizing on Middle Atlantic WMRK enclosures across multiple closets or wiring rooms in the same facility.
• Overall Dimensions — 45 x 37 x 8 inches per panel: The 8-inch dimension accounts for the panel body and mounting flanges. Confirm your rack bay and aisle clearance can accommodate the panel profile, especially in tight wiring closets where side clearance may be limited.

Integration and Compatibility

The SPN-45-36 is purpose-built for the Middle Atlantic WMRK-4536 server enclosure. If you're building out a rack enclosure system for a security operations center or IT closet, these panels close off the sides of the WMRK-4536 to reduce unauthorized access, improve airflow management at the sides, and present a finished appearance. They do not include integrated ventilation or cable management features — if airflow through the side panels is a design requirement, evaluate whether a louvered or vented panel variant is a better fit for your thermal management plan.

For integrators standardizing on rack accessories and infrastructure across enterprise or government installations, sourcing these panels alongside the WMRK-4536 enclosure through the same order simplifies receiving and installation scheduling. Because this is a drop-ship item, lead time coordination is important — factor this into your project timeline rather than treating it as stocked hardware. Pair with a rack power distribution solution to complete the enclosure build.

Frequently Asked Questions

Q: What rack enclosure is the SPN-45-36 designed to fit?

A: The SPN-45-36 is engineered specifically for the Middle Atlantic WMRK-4536 server enclosure and is also compatible with the broader WMRK rack series. It is a 45U, 36-inch-deep panel pair — verify your enclosure model and depth before ordering.

Q: Are both left and right panels included, or do I need to order separately?

A: The SPN-45-36 is sold as a pair — both left and right panels are included in a single order. No separate SKUs are needed.

Q: What are the shipping weight and dimensions for the SPN-45-36?

A: The combined shipping weight is 112 lbs. Panel dimensions are 45 x 37 x 8 inches. Plan accordingly for freight delivery and have at least two people available for unboxing and installation given the weight.

Q: Do the SPN-45-36 panels include ventilation or airflow features?

A: No. The SPN-45-36 panels are solid — they do not include louvered vents or integrated airflow features. If side-panel ventilation is a thermal management requirement for your enclosure, evaluate a vented panel variant.

Q: Is the SPN-45-36 a stocked item or does it ship direct?

A: The SPN-45-36 is a drop-ship only item. It ships directly from the manufacturer's distribution point, not from local stock. Factor lead time into your project schedule — do not treat it as same-week inventory.

Q: What finish color are the SPN-45-36 panels?

A: Black. The finish is matched to the standard WMRK-4536 enclosure color for a consistent rack appearance.

Jerry Tildsen

The SPN-45-36 (often searched as SPN 45 36) is a straightforward but frequently overlooked part of a complete WMRK-4536 enclosure build. At 112 lbs combined shipping weight for the pair, this is not a one-person job — and because it's drop-ship only, integrators who forget to include it in the initial order end up waiting on a second freight shipment while the rack sits open in a live room.

Technical Highlights:

• 45U x 36-Inch Depth Match: These panels are dimensioned to the WMRK-4536's exact 45U height and 36-inch depth — no cutting, no shimming. A mismatched depth leaves a gap at the front or rear of the enclosure that undermines both aesthetics and physical access control.
• Pair Packaging: Ordering one SKU delivers both sides, which matters on projects where procurement is line-item tracked. Split orders for left and right panels on a 45U enclosure create unnecessary PO complexity.
• Recessed Lift Handles: At this size and weight, the recessed handles aren't a convenience feature — they're the practical means of maneuvering each panel into position without damaging the enclosure or the panel finish during installation.

Deployment Considerations:

• Drop-ship lead time is a real project variable. Include the SPN-45-36 on the initial enclosure order — retrofitting after the rack is installed and populated is significantly harder than installing the panels during initial rack build-out.
• The panels are solid with no integrated ventilation. In high-density enclosures running significant thermal loads, side-panel airflow may matter. Evaluate your thermal plan before committing to solid panels; vented alternatives may be available in the WMRK accessory line.

For security operations centers and enterprise IT closets deploying WMRK-4536 enclosures where physical access restriction and a finished rack appearance are both project requirements, the SPN-45-36 is the correct factory-matched panel — not a generic aftermarket fit.
