Middle Atlantic SNE24D-4536-P1 45U 24-Inch Wide Security Network Enclosure

The Middle Atlantic SNE24D-4536-P1 is a 45U, 24-inch-wide floor-standing security network enclosure engineered for NVR stacks, server infrastructure, and network equipment deployments where depth, load capacity, and cable management actually matter. At 36 inches deep with 32.48 inches of usable internal depth, this enclosure accommodates full-depth servers, network switches, and high-density NVR chassis without the compromises you hit with shallower IT-grade racks.

Overview

The SNE Series from Middle Atlantic targets physical security and AV infrastructure — the environments where you're stacking NVRs, PoE switches, storage arrays, and UPS units in the same enclosure. The Middle Atlantic SNE product line is purpose-built for this use case, not adapted from general IT cabinetry. The SNE24D-4536-P1 lands at 45U (84.77 inches tall), a practical ceiling for most security equipment rooms without hitting standard 8-foot ceiling clearance limits. The 24-inch external width accommodates the standard 19-inch panel width with room for cable trays and vertical managers on either side.

Key Features

• 45 RU at 84.77 inches tall: Forty-five rack units gives you real density for mixed-equipment security infrastructure — a typical NVR, core switch, patch panel, and UPS deployment rarely exceeds 20-25U, leaving headroom for expansion without a second enclosure. The 84.77-inch height clears most standard doorways during installation, which matters when you're rolling this through a finished data room or security closet.
• 36-inch depth, 32.48-inch usable: The 32.48 inches of usable internal depth accommodates full-depth servers and high-capacity NVR chassis. Shallow 24-inch racks force you into short-depth or custom-mount workarounds; this enclosure eliminates that constraint. Factor the 3.52-inch difference between nominal and usable depth when planning rear cable management.
• 3,000 lb static load capacity: Few integrators fill a 45U enclosure to 3,000 lbs, but that structural margin translates directly to frame rigidity. A rigid frame means door alignment holds over time, rack rail positions stay true under vibration, and you're not dealing with warped panels two years into a multi-NVR installation.
• Passive front-to-rear airflow cooling: Passive cooling means no fan modules to fail, no fan noise, and no fan power draw. This works when your room-level HVAC handles ambient temperature — standard in most purpose-built security equipment rooms. If your deployment environment has poor ambient cooling, plan for active blanking panels or auxiliary fan units rather than relying on passive airflow alone.
• Cage-nut mounting with 100 6mm cage nuts and rack screws included: Cage-nut style rails give you flexible U positioning for any equipment mix. The 100 included cage nuts and rack screws are enough to fully populate 25 RU of 4-post equipment out of the box — you won't need a hardware kit for the initial buildout.
• Four casters and four leveling feet: The casters let you roll the enclosure into position during installation, then drop the leveling feet for a stable, vibration-damped final position. The feet also allow fine leveling on uneven floors — relevant in older buildings or warehouse security deployments where concrete slabs aren't perfectly level.
• Solid top panel with brush cable pass-through: The brush-style cable pass-through keeps the top sealed against dust and pests while allowing overhead cable runs to enter cleanly. This is standard for security equipment rooms with overhead cable trays, and it avoids the unmanaged top-of-rack cable jumble that creates maintenance headaches later.
• Lever Lock compatible: Lever Lock compatibility means the enclosure integrates with Middle Atlantic's door locking ecosystem — relevant for deployments where physical security of the rack contents is a compliance or site-security requirement.

Integration and Compatibility

The SNE24D-4536-P1 (often searched as SNE24D 4536 P1) accepts standard 19-inch rack equipment across the full 45U height. Cage-nut style rails are compatible with the broad range of network video recorders, PoE switches, patch panels, and UPS units used in commercial security infrastructure. The Lever Lock door compatibility enables keyed or access-controlled enclosure security without aftermarket hardware. If you're building out a high-density PoE switch layer alongside NVR storage, the 32.48-inch usable depth handles full-depth 1U and 2U switch chassis without rear-rail extension kits. For structured cabling integration, pair this enclosure with a rack cabinet accessories set including vertical cable managers and horizontal wire guides to keep the 45U run organized across multiple installation phases. The solid top brush pass-through aligns with standard overhead cable tray entry common in commercial security buildouts.

Frequently Asked Questions

Q: What is the usable internal depth of the SNE24D-4536-P1?

A: The usable internal depth is 32.48 inches, out of a nominal 36-inch external depth. Plan for this difference when measuring full-depth servers or NVR chassis against the rear cable management space.

Q: Does the SNE24D-4536-P1 include mounting hardware?

A: Yes. The enclosure ships with 100 6mm cage nuts and matching rack screws, enough to populate roughly 25 RU of 4-post equipment at initial buildout.

Q: What cooling method does the SNE24D-4536-P1 use?

A: Passive front-to-rear airflow. There are no fan modules included. This is appropriate for deployments with adequate room-level HVAC. If ambient cooling is insufficient, plan for auxiliary fan units or active blanking panel solutions.

Q: Does the SNE24D-4536-P1 ship with casters?

A: Yes — four casters and four leveling feet are included. The casters allow repositioning during installation; the leveling feet lock the enclosure in final position and compensate for uneven floors.

Q: What is the weight capacity of the SNE24D-4536-P1?

A: The static load capacity is 3,000 lbs, which provides substantial structural margin for fully populated NVR, storage, and switching infrastructure.

Q: Is the SNE24D-4536-P1 compatible with standard 19-inch rack equipment?

A: Yes. The panel width is 19 inches and the cage-nut rails accept standard rack equipment across all 45U of height.
