Middle Atlantic 26 Rack Units Centered CWR Series Additional Rackrail 12-24 Steel Black - CWR-RR26

Middle Atlantic CWR-RR26 26RU Centered Additional Rack Rail for CWR Series

The Middle Atlantic CWR-RR26 is a centered, additional rack rail engineered specifically for the CWR Series slide-out rack family — providing a 26-rack-unit, 12-24 threaded steel rail in a black E-Coat finish for integrators who need a third or replacement rail in a structured wiring or AV rack deployment. If your CWR rack is configured for a centered cable management path and you need an additional mounting surface without sourcing a non-OEM substitute, the CWR-RR26 is the part.

Key Features

• 26 RU Capacity (45.5 in usable height): At 45.5 inches of usable mounting height, this rail accommodates a full 26U of gear — enough for a dense security headend (NVR, PoE switches, patch panels, and access control hardware) in a single CWR enclosure without running out of rail before you run out of rack space.
• 12-24 Threaded Rail Type: The 12-24 thread standard is the dominant rack fastener in professional AV and security installations. Standard rack screws, cage nuts, and clip nuts all seat correctly — no adapters, no special hardware, no field modifications required. This matters when you are populating a rack quickly on a job site where every minute counts.
• Black E-Coat Finish: Electrophoretic coating (E-Coat) provides corrosion resistance that outlasts standard powder coat in environments with humidity variation — think server closets with intermittent HVAC, or wiring rooms near exterior walls. The finish also presents cleanly when the rack door is open during client walk-throughs.
• Steel Construction at 2.23 in Wide: At 2.23 inches wide, this rail stays within the spatial footprint of the CWR enclosure without interfering with adjacent cable runs or chassis ears. The steel substrate handles repeated torque cycles from mounting and re-mounting equipment without the rail deforming or loosening over time.
• CWR Series Compatibility (Base Series: CWR): Designed exclusively as an additional rail for the CWR slide-out rack family. This is not a universal rail — it is a manufacturer-matched component. Using the correct OEM rail eliminates fitment guesswork and ensures the centered mounting position aligns with the CWR frame geometry.
• 20-Inch Depth: The 20-inch depth matches the CWR rack enclosure's interior depth profile, so the rail runs the full usable interior length. A shorter or longer third-party rail would either leave mounting gaps near the rear or interfere with the rack's slide-out mechanism — neither is acceptable in a finished installation.
• Manageable Shipping Weight (15.4 lbs / 7 kg): At just over 15 pounds, a single technician can stage and install this rail without a lift assist. For rack builds happening in tight mechanical rooms or above suspended ceilings, that matters more than it might seem on paper.

Integration & Compatibility

The CWR-RR26 (often searched as CWR RR26) is engineered for the Middle Atlantic CWR Series slide-out rack enclosures. It functions as an additional centered rail — not a replacement for the standard left/right pair. Before ordering, confirm your CWR enclosure's rack unit depth: this rail covers 26 RU, so it must match the enclosure's unit count to align correctly with the frame mounting points.

The 12-24 thread pattern is compatible with standard rack accessories used across rack mount hardware categories including 1U patch panels, blanks, cable managers, and security appliances. If you are planning a structured rack enclosure build around an NVR, managed switch stack, and access control panel, the centered rail position in the CWR frame provides an organized pathway for front-to-back cabling without routing over equipment ears.

For integrators building out AV or security headend rooms, pairing this rail with the appropriate rack cable management accessories ensures the added rail surface contributes to — rather than complicates — the finished wire run. Consult the CWR enclosure documentation to verify the centered rail slot position before installing.

Frequently Asked Questions

Q: Is the CWR-RR26 a replacement for the standard CWR rack rails, or an additional rail?

A: The CWR-RR26 is an additional centered rack rail for the CWR Series — it is not a replacement for the standard left and right rails that come with the enclosure. It is designed for installations requiring a third, centered mounting surface within the CWR frame.

Q: What thread type does the CWR-RR26 use?

A: The CWR-RR26 uses 12-24 threaded mounting holes, which is the standard rack fastener thread used across professional AV and security installations. Standard 12-24 rack screws are compatible — no special fasteners required.

Q: How many rack units does the CWR-RR26 support?

A: The CWR-RR26 provides 26 rack units (RU) of mounting space, with a usable height of 45.5 inches (115.6 cm). Verify that your CWR enclosure is a 26RU model before ordering to ensure the rail aligns with the enclosure frame.

Q: What is the finish on the CWR-RR26?

A: The CWR-RR26 has a black E-Coat (electrophoretic) finish. E-Coat provides better corrosion resistance compared to standard powder coat, making it suitable for environments with humidity variation such as server closets or exterior wiring rooms.

Q: What are the physical dimensions of the CWR-RR26?

A: The CWR-RR26 measures 2.23 inches wide (5.7 cm), 45.5 inches in height (115.6 cm), and 20 inches in depth (50.8 cm). Shipping weight is 15.4 lbs (7 kg).

Q: Is the CWR-RR26 compatible with universal or third-party rack enclosures?

A: The CWR-RR26 is designed specifically for the Middle Atlantic CWR Series slide-out rack enclosures. It is an OEM-matched component and may not align correctly with non-CWR enclosures. Use in non-CWR frames is not supported by the manufacturer.

The CWR-RR26 is the part you order when a centered third rail is the missing piece in a CWR Series build — specifically, a 26RU centered rail with 12-24 threading and a 20-inch depth matched to the CWR enclosure interior. It is a precision fit, not a generic component, and that distinction matters at installation time.

Technical Highlights:

• 26 RU / 45.5 in usable height: Full-enclosure rail coverage for a 26U CWR frame — no gap between the rail end and enclosure frame, which matters when mounting equipment near the top or bottom of the rack.
• 12-24 threaded steel construction: Steel rail with standard 12-24 threading accepts the same fastener stock you already carry for every other rack in the installation — no secondary hardware run required.
• E-Coat finish at 2.23 in width: The electrophoretic black finish resists corrosion better than powder coat in variable-humidity environments, and the 2.23-inch width stays inside the CWR frame without crowding adjacent cable pathways.

Deployment Considerations:

• Confirm your CWR enclosure is a 26RU model before ordering — the CWR-RR26's 45.5-inch height and 20-inch depth are matched to that specific frame geometry. A unit count mismatch means the rail mounting holes will not align with the enclosure's frame.
• The CWR-RR26 is an additional centered rail, not a standard left/right replacement. If you need a left or right rail for a CWR enclosure, this is not the correct SKU — verify the rail position before requisitioning.

This rail fits cleanly in a security integrator's headend rack build where a CWR slide-out enclosure is carrying an NVR, PoE switch stack, and access control hardware and the centered rail position is needed for a structured front-to-back cable pathway. It is not a universal rack rail — deploy it where it belongs.
