Middle Atlantic Pair of Side Panels Fits MRK 4026 & WRK-40-27 Black Finish - SPN-40-267

Middle Atlantic SPN-40-267 40U Solid Side Panels for 26-27" Deep Rack Enclosures

Overview

The SPN-40-267 is a matched pair of solid black side panels designed to close out 40U Middle Atlantic rack enclosures in finished equipment rooms, AV head-end closets, and security infrastructure deployments where open rack sides are unacceptable. Each panel runs 76.06 inches tall and covers the full exterior face of a 26- to 27-inch deep rack — giving you a clean, professional enclosure without fabricating custom covers or sourcing panels from a third party. The lift-on/lift-off mounting design means panels install and remove tool-free, which matters during commissioning when you're repeatedly accessing cabling runs before the installation is finalized.

Compatibility

The SPN-40-267 is verified for use with the following Middle Atlantic 40U rack series at 26–27 inches of interior depth:

• WRK Series — including the WRK-40-27 model called out in the product designation
• MRK Series — including the MRK 4026
• VMRK Series — ventilated manager/rack combos in the same depth range
• VRK Series — ventilated rack enclosures
• DRK Series — durable rack line at matching 26–27" depth

Depth compatibility is 26–27 inches — confirm your rack's interior depth before ordering. Panels are not interchangeable across rack heights; a 40U panel will not fit a 44U or 36U frame.

Installation Notes

The lift-on/lift-off design requires no tools and no hardware for panel attachment — the panel seats onto the rack frame and lifts clear for access. This makes it practical in staged installs where side panels go on last, after all cable management and rear-panel work is complete. Because these are solid (not vented) panels, verify that your rack's thermal load is handled by top-of-rack exhaust or active ventilation rather than side airflow before enclosing the chassis.
