Middle Atlantic Rotating Sliding Base 14in. Useable Depth - REB14

Middle Atlantic REB14 Rotating Sliding Base, 14-Inch Usable Depth

Overview

The Middle Atlantic REB14 is an in-cabinet rotating and sliding base designed for equipment that needs to be accessed from multiple angles without being fully removed from the rack. At 14 inches of total depth and 13 inches of usable depth, it's sized for mid-depth components — think smaller NVRs, patch panels, or AV control units — where you need reach-behind access without pulling the unit. If you've ever had to wrestle a device out of a cabinet just to get at rear connectors, this is the hardware that solves that problem at the rack level.

Part of the broader Middle Atlantic rack and cabinet accessories line, the REB14 is built for in-cabinet installation and pairs naturally with Middle Atlantic's standard rack enclosures. It's a practical fit in surveillance head-end rooms, AV racks, and security operations closets where servicing equipment in place is the norm rather than the exception.

Key Features

• 13-Inch Usable Depth: The 13 in (33 cm) of usable depth (vs. 14 in total) gives you a realistic working envelope for most mid-depth 1U and 2U units. Know your equipment's actual depth before ordering — anything pushing past 13 inches won't seat fully and may obstruct the slide mechanism.
• 75 lb Weight Capacity: The 75 lb (34 kg) load rating comfortably covers most NVRs, smaller servers, and dense patch assemblies. If you're planning to stage a loaded NVR with installed drives, verify the combined weight stays under this threshold — hard drives add up fast on high-channel recorders.
• Rotating and Sliding Action: The combination of slide-out reach and rotational movement means you can access rear-panel connections without disconnecting cables first. This is the key differentiator over a standard fixed shelf — meaningful in tight cabinet builds where cable slack is limited.
• 17.13-Inch Width: At 17.13 in (43.5 cm) wide, the REB14 is designed to fit standard 19-inch rack enclosures. Verify your specific cabinet's interior rail-to-rail dimension before mounting, as some narrow-depth or non-standard enclosures vary from the 19-inch norm.
• 2.02-Inch Height Profile: The 2.02 in (5.1 cm) height means the base itself occupies roughly 1U of vertical space in your cabinet. Account for this in your rack U planning — the mounted equipment will add its own height on top.
• In-Cabinet Rack Type: The REB14 is explicitly rated for in-cabinet use, meaning it's engineered for the enclosed environment of a rack cabinet rather than open-frame or wall-mount rail setups. Don't attempt to adapt it to open-frame racks — the mounting geometry and load path are designed for enclosed cabinet side rails.

Integration and Compatibility

The REB14 integrates with rack accessories and mounting hardware from the Middle Atlantic product family. It installs into standard in-cabinet rack enclosures with conventional rail mounting. When deploying alongside network video recorders or other rear-access-dependent equipment, the slide-out and rotate function eliminates the need to disconnect cable runs during routine maintenance — a real time saver in dense head-end builds. For full rack infrastructure planning, pair with appropriate cable management and blanking panels to maintain airflow and organization in the cabinet.

No special tools or custom hardware are documented in the evidence for installation. Verify rail compatibility with your specific Middle Atlantic or third-party cabinet before ordering, as rail spacing and depth tolerances vary across enclosure families.

Frequently Asked Questions

Q: What is the maximum weight the REB14 can support?

A: The REB14 is rated for a maximum weight capacity of 75 lbs (34 kg). Verify the combined weight of your equipment — including installed drives or modules — stays under this limit before mounting.

Q: What is the difference between the 14-inch depth and the 13-inch usable depth?

A: The 14-inch figure is the overall depth of the base assembly. The usable depth — the actual space available for your equipment — is 13 inches (33 cm). Equipment with a body depth close to or exceeding 13 inches may not seat or slide properly.

Q: Is the REB14 compatible with standard 19-inch rack cabinets?

A: The REB14 is designed for in-cabinet use at 17.13 inches wide, which fits standard 19-inch rack enclosures. Confirm your cabinet's interior rail-to-rail dimension before ordering, as tolerances vary between manufacturers and enclosure models.

Q: How much vertical rack space does the REB14 occupy?

A: The base itself measures 2.02 inches (5.1 cm) in height, occupying roughly 1U of vertical space. Your mounted equipment adds additional height on top of that, so plan your U budget accordingly.

Q: Can the REB14 be used in open-frame rack setups?

A: No. The REB14 is rated specifically for in-cabinet rack installations. It is not designed or documented for use with open-frame or wall-mount rail configurations.

Q: What type of equipment is the REB14 best suited for?

A: The REB14 works well for mid-depth 1U and 2U equipment — NVRs, AV controllers, smaller servers, or patch units — where rear-panel access is needed during maintenance without fully removing the device from the cabinet.

The REB14's 75 lb weight capacity and 13-inch usable depth are the two numbers I check first on every deployment. In a surveillance head-end cabinet, you're often stacking an NVR with a full drive array alongside switch modules and power distribution — the 75 lb rating covers most NVR configurations without concern, but it's worth a quick scale check before mounting anything dense. The REB14 earns its place in builds where rear-port access is routine rather than exceptional.

Technical Highlights:

• 13-Inch Usable Depth: The 1-inch difference between the 14-inch total and 13-inch usable depth matters — equipment rated at exactly 14 inches nominal depth (common with some 2U NVRs) may bind the slide. Always measure actual chassis depth, not panel-to-panel spec sheet depth.
• 2.02-Inch Height Profile: At just over 2 inches, the base adds minimal vertical overhead. In a fully loaded cabinet, that 1U footprint is the difference between fitting your build plan and going to a larger enclosure.
• 17.13-Inch Width: Sized for 19-inch standard enclosures, which covers the vast majority of Middle Atlantic cabinets. Confirm your cabinet's internal rail width before ordering — non-standard or narrow-depth variants occasionally run tighter than 17 inches clear.

Deployment Considerations:

• In surveillance operations rooms with multiple cabinets, the rotating action is most valuable on the units you service most often — NVRs getting drive swaps, or recorders requiring periodic firmware access via rear USB. Position the REB14 at a height that allows comfortable rotation without interference from adjacent cable management arms.
• The in-cabinet-only rating is a hard constraint. If your project spec calls for open-frame rack deployment, the REB14 is not the right product — the mounting geometry doesn't transfer and the load path isn't validated for open-rail use.

For a security operations head-end where the NVR or controller needs quarterly drive maintenance without a full teardown, the REB14 is the right hardware at the right weight class — particularly in Middle Atlantic enclosed cabinets where rear access would otherwise require a full unrack operation.
