Middle Atlantic 15 Space Rotating Sliding Rail System 250 Lb Capacity - SRSR-4-15

Middle Atlantic SRSR-4-15 15U Rotating Sliding Rail System

Overview

The Middle Atlantic SRSR-4-15 is a 15-rack-unit rotating slide-out rail system designed for in-cabinet equipment installations where rear-access without pulling gear offline is a real operational requirement. At 250 lb rated capacity with a 17.25-inch usable depth, it handles loaded NVR shelves, dense patch concentrations, and multi-device AV or security rack builds — not just lightweight accessories. If you're integrating surveillance recorders, managed switches, or encoder stacks inside a fixed cabinet and need to service the rear of the equipment without a full decommission, the SRSR-4-15 (often searched as SRSR 4 15) solves that problem mechanically rather than procedurally.

Manufactured in the USA and TAA-compliant, this system suits government facilities, federal installations, and enterprise procurement environments where country-of-origin documentation is a bid requirement. The flat black powder coat finish matches standard rack aesthetics without calling attention to itself inside finished enclosures.

Key Features

• 250 lb (113.4 kg) Weight Capacity: Handles fully loaded NVR trays, dense switch stacks, and multi-drive storage arrays without deflection concerns. That's enough headroom for a high-channel recorder with populated drive bays — not just a KVM tray or patch panel.
• 15 Rack Units of Usable Space: 15 RU across a 26.25-inch (66.7 cm) usable height accommodates the typical depth of a mid-range surveillance recorder stack. You're not limited to a single device — a recorder, a managed PoE switch, and a fiber converter can coexist without crowding.
• 17.25-Inch Usable Depth (43.8 cm): Fits the majority of 1U and 2U rack-mount equipment with room to manage cable egress at the rear. Most NVRs and switches fall well within this envelope; measure your deepest unit before assuming clearance on anything approaching 20 inches.
• Rotating Slide-Out Mechanism: The system slides forward and rotates, exposing rear panel access without removing the unit from the cabinet. For installations where cabling is permanent and equipment is serviced in place — think wall-mounted or closet cabinets — this eliminates the need to physically extract and re-cable every service cycle.
• 10-32 Rack Rail Threading: Standard 10-32 tapped rails accept the full range of rack-mount hardware without adapters or cage nuts. Most professional AV and security rack equipment ships with 10-32 screws by default, so panel alignment and mounting are straightforward.
• In-Cabinet Rack Type: Engineered specifically for enclosed cabinet integration — this is not a standalone open-frame rail. The mounting geometry assumes a parent enclosure; verify your cabinet's internal rail spacing and slide clearance before ordering.
• Flat Black Powder Coat Finish: Durable, non-reflective surface finish holds up to repeated slide cycles and tool contact without chipping or glare issues in camera-monitored server rooms or IDF closets.
• TAA Compliant, Made in the USA: Satisfies federal procurement requirements under the Trade Agreements Act. Origin documentation is available for bid packages — relevant for GSA schedule orders, municipal AV integrations, and DOD facility work.

Integration & Compatibility

The SRSR-4-15 installs inside standard 19-inch rack enclosures using the cabinet's existing rail mounting points. The overall footprint is 19.13 inches wide by 19.14 inches deep — plan for the full slide-out travel distance beyond the cabinet front when positioning in tight IDF closets or wall-mounted enclosures. Clearance in front of the cabinet must accommodate the full extension plus rotation arc; in confined spaces, measure twice before committing the cabinet location.

For rack systems and enclosures, this slide-out unit pairs with Middle Atlantic's enclosed cabinet line. If you're building a security rack for a network video recorder installation, the 15 RU capacity typically covers a primary recorder, a managed PoE switch, and ancillary gear in a single rotating assembly. Review the rack accessories category for complementary blanks, cable management, and brush panels that complete the enclosure build.

Shipping weight is 58 lbs (26.3 kg) for the assembly. Factor this into lift planning for overhead or wall-mounted cabinet installations — a two-person install is practical at this weight class, particularly when the parent cabinet is already populated.

Frequently Asked Questions

Q: Is the Middle Atlantic SRSR-4-15 TAA compliant?

A: Yes. The SRSR-4-15 is TAA compliant and manufactured in the USA, making it suitable for federal, municipal, and GSA schedule procurement where country-of-origin documentation is required.

Q: What is the weight capacity of the SRSR-4-15?

A: The SRSR-4-15 is rated at 250 lbs (113.4 kg) — sufficient for fully loaded NVRs, populated switch stacks, and multi-device security rack configurations.

Q: What rack rail thread type does the SRSR-4-15 use?

A: It uses standard 10-32 tapped rails, which accept the majority of professional rack-mount AV and security equipment without cage nut adapters.

Q: Will the SRSR-4-15 fit inside my existing 19-inch rack cabinet?

A: The overall dimensions are 19.13 inches wide and 19.14 inches deep. It is designed as an in-cabinet rack system, so it requires a compatible enclosed 19-inch enclosure. Verify your cabinet's internal rail spacing and that adequate front clearance exists for the full slide-out and rotation arc before installing.

Q: How much usable depth does the SRSR-4-15 provide for equipment?

A: The usable depth is 17.25 inches (43.8 cm). Most 1U and 2U rack-mount NVRs and switches fit within this envelope, but verify the depth of any unit approaching 18–20 inches before assuming compatibility.

Q: Is the SRSR-4-15 a standalone open-frame rack or does it require a cabinet?

A: It is an in-cabinet system — it mounts inside an existing enclosed 19-inch cabinet. It is not a standalone open-frame rail and should not be used as a freestanding unit.

Ted Perry

The spec that earns the SRSR-4-15 a spot in a serious security rack build is the 250 lb weight capacity paired with 17.25 inches of usable depth — that combination lets you load it with real surveillance hardware, not just lightweight accessories, while still being able to rotate the assembly and reach the rear panel of every device without pulling cables. That rear-access capability is the entire justification for this product class in an enclosed cabinet environment.

Technical Highlights:

• 250 lb Rated Capacity: At 113.4 kg, this handles a populated NVR chassis, a managed PoE switch, and a fiber converter simultaneously — verified by the manufacturer spec, not an estimate. Overloading a rotating slide mechanism is how you damage both the rail and the equipment; stay within the rated limit and you won't.
• 17.25-Inch Usable Depth: This is the number to cross-reference against your equipment list before ordering. The majority of 1U rack-mount NVRs and managed switches land between 12 and 17 inches; anything deeper than 17.25 inches won't seat properly and may prevent the slide from closing.
• TAA Compliant / Made in USA: For government and municipal integrations, this is a procurement checkbox, not a marketing note. The SRSR-4-15 satisfies federal TAA requirements and ships with verifiable country-of-origin documentation.

Deployment Considerations:

• Plan front-of-cabinet clearance before committing to a cabinet location. The slide-out and rotation arc requires open space in front of the enclosure — in a tight IDF closet or recessed wall niche, this can be a hard constraint that rules out the rotating mechanism entirely.
• Shipping weight is 58 lbs for the assembly alone. If the parent cabinet is already mounted and populated, two-person installation is the practical minimum, particularly for overhead or elevated wall-mount positions.

This system is a natural fit for municipal security operations centers and government facility IDF closets where TAA compliance is mandatory, cabinet space is fixed, and the expectation is that equipment gets serviced in place rather than decommissioned for rear-panel access. If your deployment scenario involves a standard open-frame rack with unrestricted rear access, the rotating mechanism adds cost without adding value — specify accordingly.
