Middle Atlantic SNE24D-2436-P1 24U Floor-Standing Server Rack Enclosure
The Middle Atlantic SNE24D-2436-P1 is a 24U, 36-inch-deep floor-standing rack enclosure built for equipment-dense security and IT deployments where airflow, cable management depth, and structural rigidity all matter. At 48 inches tall and 24 inches wide, it accommodates standard 19-inch panel equipment across 24 rack units — enough space for a mid-scale NVR stack, PoE switch layer, patch panels, and UPS in a single enclosure without crowding cables into the rear. This is a purpose-built enclosure for integrators who need a reliable, passive-cooled rack that ships with the hardware to populate it immediately.
Overview
The SNE Series targets security system integrators, AV installers, and IT teams building out server rooms or IDF closets where a full-depth, floor-standing rack is preferred over a wall-mount or open-frame option. The SNE24D-2436-P1 (often searched as SNE24D 2436 P1) ships as a fully assembled enclosure with adjustable rack rails, locking side panels, and a vented front door — the core infrastructure is ready to rack on delivery. The 220 lb shipping weight reflects a genuinely heavy-duty steel frame; plan accordingly for freight receiving and positioning before populating equipment.
Key Features
- 24U Rack Capacity in a 36-Inch Depth: Twenty-four rack units of usable space with 36 inches of internal depth means full-depth servers, NVRs, and large UPS units fit without the rear cable tray becoming a problem. Shallow 24-inch or 29-inch racks force cable routing compromises on deep equipment — this depth eliminates that issue.
- 70% Open-Area Vented Front Door: The front door is 70% open, enabling passive front-to-rear airflow without powered fan trays in most security equipment environments. Active recording servers and PoE switches generate sustained heat; a 70% open face lets that heat exit naturally in climate-controlled spaces, reducing the need for add-on cooling accessories.
- Passive Front-To-Rear Cooling Architecture: Airflow moves front-to-rear by design — the same direction most 1U and 2U equipment exhausts heat. This alignment means you're not fighting the enclosure's airflow pattern with your equipment's built-in fans, which is a common problem with poorly designed racks.
- Two Pairs of Adjustable Cage-Nut Rail Systems: Both rail pairs are adjustable, so equipment of varying depths mounts correctly without shimming. Standard 19-inch panel width is supported across all 24U. The included 100 cage nuts and rack screws mean you're not hunting for hardware before the first piece of equipment goes in.
- Split Flush-Mount Locking Side Panels: Side panels lock independently and sit flush — no external protrusions that add to the footprint in tight IDF closets or server rooms. The split design allows single-side removal for cable work without fully disassembling the enclosure.
- Solid Top Panel: The solid top (not vented) keeps dust and debris from entering through the top — relevant in warehouse, manufacturing, or basement mechanical environments where airborne particulate is a factor. If top-exit cable management is needed, knockouts are the expected modification path.
- Floor-Standing Mounting with 220 lb Frame: At 220 lbs unloaded, this enclosure is not moving once positioned and loaded. Floor-standing installation is appropriate for any deployment where wall-mounting capacity is a concern — concrete-block or steel-stud walls where anchoring a loaded rack is not practical.
- 19-Inch Standard Panel Width: Universal compatibility with all standard rack-mount equipment — switches, NVRs, patch panels, KVM drawers, UPS units. No proprietary rail system to work around.
Integration & Compatibility
The SNE24D-2436-P1 accommodates all standard 19-inch rack-mount equipment up to the internal depth limit imposed by the rail position. With 36 inches of external depth, actual usable depth between rails will depend on rail positioning — typical usable depth on SNE Series enclosures supports full-depth 1U through 4U servers and large-format UPS units. Network video recorders, managed PoE switches, patch panels, and fiber distribution units all install directly on the adjustable cage-nut rails. This enclosure pairs naturally with PoE switches and UPS systems as the physical backbone of a rack-based security infrastructure. For integrators building out surveillance head-end rooms or IDF closets, the Middle Atlantic rack and enclosure line offers a matched family of accessories including blanking panels, vertical cable managers, and power distribution units that mount directly in this frame. Consult a rack selection guide to match enclosure depth and U-count to your specific equipment list before ordering.

Frequently Asked Questions
Q: What is the rack unit capacity of the SNE24D-2436-P1?
A: The SNE24D-2436-P1 provides 24U of rack space on standard 19-inch adjustable cage-nut rails. Total enclosure height is 48 inches.
Q: Does the SNE24D-2436-P1 include cage nuts and screws?
A: Yes. The enclosure ships with 100 6mm cage nuts and rack screws — enough to populate all 24U without sourcing additional hardware.
Q: What is the depth of the SNE24D-2436-P1 and will full-depth servers fit?
A: The external depth is 36 inches. This accommodates full-depth rack servers, large UPS units, and deep NVR appliances. Actual usable rail-to-rail depth depends on rail positioning within the enclosure.
Q: Does the SNE24D-2436-P1 require active cooling or fan trays?
A: The enclosure uses passive front-to-rear airflow through a 70% open-area vented front door. In climate-controlled spaces with typical security or IT equipment loads, active cooling accessories are not required, though they can be added if needed.
Q: Can the side panels be removed for cable access?
A: Yes. The split flush-mount locking side panels can be removed independently on each side, allowing cable work without disassembling the entire enclosure.
Q: How much does the SNE24D-2436-P1 weigh?
A: The enclosure weighs 220 lbs. Plan for freight delivery and have adequate personnel or equipment for positioning before loading rack equipment.
The SNE24D-2436-P1 is the enclosure I spec when a customer needs a mid-density security head-end in a server room or IDF closet and doesn't want to deal with cooling headaches. That 70% open-area vented front door is the spec I look at first — in a conditioned room, it means a full load of NVRs and switches stays passively cooled without adding fan trays, which is one less thing to maintain and one less thing to fail at 2 a.m.
Technical Highlights:
- 36-Inch External Depth: Gives you room for full-depth rack equipment — large-format UPS units, 2U NVR appliances, and deep PoE switch chassis all mount without rear-panel cable pinch. Shallower enclosures in the 24- to 29-inch range force cable routing compromises that create airflow and maintenance problems down the road.
- 100 Included Cage Nuts and Screws: Enough hardware to fully populate all 24U on day one. Small thing, but showing up to a job and needing to source M6 cage nuts before racking anything is a real delay — Middle Atlantic ships them in the box.
- 220 lb Steel Frame: This is a heavy enclosure that stays put under a full load. Floor-standing installation means no wall anchor load calculations needed — relevant in older buildings where wall construction varies and anchor capacity is uncertain.
Deployment Considerations:
- At 220 lbs unloaded, freight receiving and in-room positioning require planning — a loaded SNE24D-2436-P1 will need a pallet jack or multi-person crew to move into its final location before equipment is installed. Measure door and elevator clearances before delivery.
- The solid top panel is appropriate for most environments but blocks top-exit cable routing without modification. If overhead ladder tray or conduit entry is in the plan, factor in top-panel knockout work before the enclosure is positioned and loaded.
This enclosure is the right call for a corporate security head-end or campus IDF room where the equipment list runs 10–20 rack units of recording, switching, and power hardware and the room is climate-controlled — passive cooling handles the load, the 36-inch depth handles the equipment, and the locking panels handle the physical security requirement without a separate cabinet overlay.
