Middle Atlantic SRSR-4-23 Slide-Out Rotating In-Cabinet Rack System

Overview

The Middle Atlantic SRSR-4-23 is a 23-rack-unit slide-out, rotating rack system designed for in-cabinet deployments where rear access to cabling and equipment is a real operational requirement — not an afterthought. With a 250 lb (113.4 kg) weight capacity and 17.25 inches of usable depth, it handles dense security, AV, and IT equipment loads without compromise. If you've ever had to wrestle with a fixed rack in a tight closet to reach a patch panel or NVR at 2 a.m., this is the product that solves that problem permanently. Sourced factory-new, the SRSR-4-23 (often searched as SRSR 4 23) ships from a USA manufacturing origin and carries TAA compliance for government and federally funded projects.

The SRSR system fits into rack systems and enclosures that demand full front-and-rear access without pulling equipment from the cabinet. It pairs naturally with Middle Atlantic rack infrastructure for integrators standardizing on a single manufacturer ecosystem.

Key Features

• 23 RU Capacity with 17.25" Usable Depth: At 40.25 inches of usable height and 17.25 inches of usable depth, this rack accommodates full-depth 1U and 2U NVRs, managed PoE switches, and UPS units side by side. The usable dimensions are what matter for equipment fit — not the overall chassis footprint — and 17.25" handles the majority of 1U security appliances without force-fitting.
• 250 lb (113.4 kg) Weight Capacity: A loaded 23U security rack with NVRs, drives, and a UPS can push 150–200 lbs without much effort. The 250 lb rating gives meaningful headroom above typical real-world loads, so you're not engineering around a weight budget on every shelf placement.
• Slide-Out, Rotating Design: The slide-and-rotate mechanism is the core reason to specify this rack over a fixed in-cabinet rail set. Equipment can be pulled forward and rotated to expose the rear panel — useful for cable management changes, drive swaps, or troubleshooting on NVRs and servers that don't have front-accessible interfaces. No need to partially unrack equipment to reach rear connectors.
• 10-32 Rack Rail Type: Standard 10-32 threaded rails are compatible with the cage nut and screw hardware used across virtually all 1U/2U rack-mount security and IT equipment. No adapters, no proprietary hardware — standard installation practice applies.
• Flat Black Powder Coat Finish: The powder coat finish is a practical choice in populated equipment rooms and closets — it resists corrosion, doesn't show fingerprints under IR camera review, and holds up to the cleaning products used in equipment rooms. Aesthetically neutral in dark-interior cabinets.
• TAA Compliant, USA Origin: The Federal Operations country of origin is confirmed as USA, and the unit is TAA compliant. For federal integrators, GSA schedule projects, DoD installations, or any project with Buy American Act requirements, this closes the compliance checkbox without substitution risk.
• Compact Overall Footprint — 19.13" W x 43.25" H x 19.14" D: The overall depth of 19.14 inches fits inside standard 24-inch-deep cabinets with room for rear cabling, while the 19.13-inch width aligns to standard EIA 310 rack width. Verify your cabinet's interior usable depth before ordering — this unit needs sufficient clearance to slide and rotate freely.

Integration & Compatibility

The SRSR-4-23 is an in-cabinet rack system and is compatible with Middle Atlantic enclosures and third-party cabinets that provide adequate interior depth clearance for the slide-and-rotate travel range. The 10-32 threaded rail system is compatible with standard rack-mount equipment from all major network video recorder and networking hardware manufacturers. For integrators building out structured security closets, this rack pairs well with managed PoE switches and NVR appliances that benefit from rear-panel access without full de-racking. Confirm cabinet interior width and depth specifications with Middle Atlantic's cabinet lineup before combining with a new enclosure purchase.

Frequently Asked Questions

Q: Is the Middle Atlantic SRSR-4-23 TAA compliant?

A: Yes. The SRSR-4-23 is TAA compliant and carries a USA Federal Operations country of origin, making it suitable for government, GSA schedule, and federally funded projects with domestic sourcing requirements.

Q: What is the weight capacity of the SRSR-4-23?

A: The SRSR-4-23 is rated for 250 lbs (113.4 kg), providing sufficient headroom for fully loaded security and IT equipment configurations including NVRs, managed switches, and UPS units.

Q: What rack rail type does the SRSR-4-23 use?

A: The SRSR-4-23 uses standard 10-32 threaded rack rails, compatible with the cage nut and screw hardware used across virtually all standard 1U and 2U rack-mount equipment.

Q: What are the usable dimensions of the SRSR-4-23?

A: Usable height is 40.25 inches (102.2 cm) and usable depth is 17.25 inches (43.8 cm). The overall chassis dimensions are 19.13" W x 43.25" H x 19.14" D. Equipment fit should be evaluated against the usable depth, not the overall depth.

Q: Can the SRSR-4-23 be used as a standalone open rack or only inside a cabinet?

A: The SRSR-4-23 is classified as an in-cabinet rack system. It is designed to mount inside an enclosure cabinet — it is not a freestanding open-frame rack. Verify your enclosure's interior clearance accommodates the slide and rotation travel of this unit.

Q: What finish does the SRSR-4-23 have?

A: The SRSR-4-23 features a flat black powder coat finish, which is corrosion-resistant and standard for equipment room and closet deployments.

Ted Perry

The spec I always check first on a slide-out rotating rack is weight capacity relative to the intended load, and the SRSR-4-23's 250 lb rating is the number that makes this unit credible for real security integrations — not just AV light-load installs. A 23U bay loaded with a multi-bay NVR, a managed PoE switch, a 1U UPS, and a patch panel will routinely hit 130–180 lbs; having 70+ lbs of headroom means you're not re-engineering the shelf layout every time a client wants to add a device.

Technical Highlights:

• 17.25" Usable Depth: Most 1U NVRs and managed switches fall between 12" and 17" in depth. The SRSR-4-23's 17.25" usable depth sits right at the ceiling for standard appliances — you can mount full-depth equipment without shimming or forcing. That extra 1–2" margin over shallower rack systems matters when cable dressing adds thickness at the rear panel.
• 10-32 Threaded Rails: This is the correct rail standard for commercial security and IT gear. Integrators who've dealt with square-hole UNS rails and mismatched cage nuts will appreciate that 10-32 is universally supported — no adapter kits, no field fabrication, standard hardware throughout.
• TAA Compliant / USA Origin: For government end-users, this is a line-item requirement on many SOWs. The SRSR-4-23 clears that gate without substitution. Factor this in early when quoting federal or municipal surveillance room builds — it simplifies procurement review considerably.

Deployment Considerations:

• Before ordering, measure your enclosure's interior usable depth carefully. The SRSR-4-23's overall depth is 19.14" and it needs travel clearance inside the cabinet to slide and rotate freely — a tight cabinet that's exactly 19" interior depth won't work. Middle Atlantic's own enclosure lineup is the safe pairing; third-party cabinets need depth verification against the slide mechanism travel range, not just the chassis dimension.
• The 61 lb shipping weight means this ships freight, not parcel. Plan for lift-gate delivery or dock access at the installation site — this is not a UPS-ground item to drop at a residential or small office address without advance coordination.

The SRSR-4-23 is the right specification for a security operations room or IT closet where 23U of equipment needs to remain fully accessible without removing devices from the rack — specifically physical security deployments with NVR arrays, access control panels, and cabling infrastructure that gets serviced on a recurring maintenance schedule.
