Middle Atlantic 20RU Rack Rail for RFR Series Racks - 10-32 Threaded

The Middle Atlantic RFR-ERRK-20 rear rack rails are purpose-built for demanding professional environments where reliability and precision matter. Engineered to fit the RFR series racks, these heavy-gauge, 10-32 threaded rails deliver secure, durable mounting for your most critical equipment. Sold in pairs, they provide balanced support across the rack, helping to maintain accurate alignment and reduce wear during installations, service, and daily use. Whether you’re outfitting a data center, AV installation, recording studio, or industrial control room, these rails are designed to withstand heavy loads, frequent insertions and removals, and the rigors of long-term operation while preserving performance and rack integrity. With a focus on rugged construction and straightforward installation, Middle Atlantic delivers a trusted solution that minimizes downtime and keeps gear exactly where you need it.

• Premium construction for demanding environments: Built with heavy-gauge metal and precision welds to resist bending and flex under full rack loads. The resilient material and robust manufacturing process ensure long-term structural stability, limiting sag and deformation even when multiple devices are mounted in dense 20U configurations. This translates into reliable performance across installations that require steady, repeatable mounting over years of service.
• 10-32 threaded rear rails: The standard 10-32 threading provides broad compatibility with a wide range of rack-mount equipment and accessory hardware. The rear rail design offers secure anchoring for rear-mounted components, keeping gear firmly in place during transport, vibration, or small-scale seismic activity. This threading is a recognized industry standard, making it easier to source compatible screws and fasteners from multiple suppliers without compromising security or alignment.
• RFR series compatibility: Specifically engineered for Middle Atlantic RFR series racks, ensuring precise fit and alignment with the unique mounting holes, chassis dimensions, and overall tolerances of these enclosures. By matching the RFR’s rail-to-frame geometry, the rails preserve the rack’s overall rigidity and spacing, which is critical when stacking multiple devices, cables, and accessories in a compact footprint.
• Sold in pairs for balanced support: Each purchase includes two rails, designed to be mounted on opposite sides of the rack for even load distribution. Using rails in pairs helps maintain symmetry, prevents skew, and supports safer handling when sliding equipment in and out. This paired configuration is ideal for 20U rack layouts where stability and alignment across the entire rack height are essential for equipment longevity and accessibility.
• Secure, durable mounting with minimal maintenance: The combination of heavy-gauge materials and precise threading provides a secure, vibration-resilient mount that reduces micro-movements that can loosen connections over time. The result is improved equipment longevity, fewer service interruptions, and a more dependable installation—especially in environments with frequent gear changes or heavy devices that impose higher mounting forces on rails and chassis.

How to install Middle Atlantic 20RU Rack Rail

Installing the Middle Atlantic 20RU Rack Rail for RFR Series Racks is designed to be straightforward, minimizing downtime and ensuring a precise fit. Follow these steps to achieve secure mounting and optimal alignment for your rack equipment:

• Prepare the rack and hardware: Gather the two rear rails and the appropriate 10-32 hardware. Confirm you are installing the rails on the correct side of the rack as specified by your RFR series model to ensure proper clearance andline-up with the chassis holes.
• Align rails with mounting holes: Position each rail so that its screw holes line up with the corresponding chassis holes on the rear of the rack. Use a light touch to hold the rails in place while you verify that the rails sit parallel to the horizontal plane and are square with the rack’s sides. This initial alignment is critical to prevent binding during the mounting process and to maintain clean cable paths behind the equipment.
• Secure the rails with 10-32 hardware: Insert the 10-32 screws through the rail holes and finger-tighten to hold the rails in position. Ensure threads engage smoothly without cross-threading. Use a screwdriver to snug the hardware, taking care not to overtighten, which can distort the rail or affect the rack’s structure.
• Check alignment and clearance: Once both rails are attached, verify that they run parallel to each other and to the rack’s frame. Confirm there is adequate clearance for equipment in the 20U height, including front-to-back depth and any protruding connectors. A quick check with a level can help confirm square mounting and prevent gear from binding during operation.
• Mount equipment and perform a test fit: With the rails secured, slide your equipment into the rack and verify that the chassis aligns with the rail slots. Secure the equipment according to its own mounting hardware, ensuring that all screws engage properly with the rails. Perform a light test insertion and removal to confirm smooth operation and stability before fully populating the rack.
• Final inspection: Re-check the security of all fasteners, ensure there is no interference with cabling, and confirm that the overall rack remains level. A final pass with a torque-limiter screwdriver can help maintain consistent tightening and prevent any over-stressing of the rails or rack frame.

Frequently asked questions

• Q: What racks are compatible with the Middle Atlantic 20RU Rack Rail?

  A: These rails are designed for the Middle Atlantic RFR series racks and utilize standard 10-32 threaded fasteners for secure rear mounting. While they are optimized for RFR racks, check the mounting hole pattern and clearance of your specific enclosure to ensure proper fit. If your rack uses a non-standard rear rail pattern, you may need adapter solutions or different hardware.

• Q: Do the rails come with hardware?

  A: The product listing specifies 10-32 threaded rear rails sold in pairs. While screws and related mounting hardware are typically included with the rails themselves, it is always best to verify the hardware contents on the packaging or product page to ensure you have the necessary fasteners for your installation.

• Q: Can I use these rails for heavy equipment and frequent maintenance?

  A: Yes. The rails are described as heavy-gauge and durable, designed to withstand the demands of heavy installations and repeated insertions and removals. This makes them suitable for environments where equipment changes are common and reliability is critical.

• Q: Are these rails adjustable in depth or angle?

  A: The 10-32 rear rail system is typically designed for fixed mounting within the rack frame. They provide a stable, square mounting surface but do not usually offer depth or angle adjustment beyond standard rail-to-chassis alignment. Always follow the rack manufacturer’s installation guidance for best results.

• Q: Where can I find the exact specifications (dimensions, weight, and tolerances) for these rails?

  A: For exact measurements and official specifications, refer to the specifications section of the product page on ec.synnex.com using the product’s UPC or SKU as reference. This source provides the authoritative data you need to confirm compatibility with your rack and equipment.
