Middle Atlantic Rackrail 10-32 5 Rack Units DLBX Series Steel Black Powder Coat finish - DLBX-RR5

Middle Atlantic DLBX-RR5 5RU 10-32 Replacement Rack Rail

Overview

The Middle Atlantic DLBX-RR5 is a 5-rack-unit, 10-32 threaded replacement rack rail designed specifically for the DLBX series slide-out drawer enclosures. If you're expanding a DLBX chassis or replacing a damaged rail in an existing installation, the DLBX-RR5 delivers the exact steel construction and mounting geometry the series demands — no improvising with generic hardware that may not align with DLBX tolerances. At 20 inches deep (50.8 cm), the rail accommodates the full DLBX drawer depth, keeping equipment properly supported across its entire travel range.

This is purpose-built hardware for a specific job. The 10-32 thread pattern is the industry standard for rack-mount equipment, so any 10-32-tapped rack gear you're mounting into a DLBX drawer will thread directly into the DLBX-RR5 without adapters. Shipped as a single rail (Package Count: 1), the DLBX-RR5 (often searched as DLBX RR5) lets you source exactly what you need — one rail at a time — rather than pulling a full hardware kit when only one component requires attention.

Key Features

• 5 Rack Units of usable height (8.75 in / 22.2 cm): Enough space to mount a multi-channel audio processor, a compact NVR, or a patch panel segment inside a DLBX slide-out drawer. Five RU strikes a practical balance — deep enough to carry meaningful equipment, shallow enough to keep the drawer extension manageable in tight rack environments.
• 10-32 thread standard: The 10-32 rack rail thread is the default for virtually all rack-mount AV and network gear. Using a rail with the correct thread spec means your equipment screws seat properly without cross-threading or stripped fasteners — a detail that matters when you're assembling inside a slide-out drawer with limited wrench clearance.
• 20-inch rail depth (50.8 cm): Matches the full usable depth of the DLBX drawer chassis. A rail that's undersized relative to chassis depth leaves rear equipment unsupported and places bending stress on front-panel fasteners. The full 20-inch spec ensures the load is distributed along the rail's entire length.
• Steel construction with black powder coat finish: Steel rails handle the cyclic stress of repeated drawer extensions and retractions without fatigue creep that can occur with thinner materials. The black powder coat finish resists abrasion from equipment slides and maintains a consistent appearance inside the chassis.
• DLBX series matched geometry: Designed specifically for the DLBX base series, the DLBX-RR5 mounts with confidence that hole patterns and rail engagement points align with the enclosure's original design intent — not a universal approximation.
• Lightweight at 1.7 lbs (0.8 kg): The rail itself adds minimal overhead to the drawer's total load capacity, leaving the full weight budget for the equipment being mounted rather than the structural hardware.

Integration & Compatibility

The DLBX-RR5 is engineered exclusively for the Middle Atlantic DLBX series slide-out drawer enclosures. It is not a universal rack rail and should not be installed in non-DLBX chassis — rail depth, mounting tab geometry, and engagement points are specific to the DLBX family. If you're sourcing this rail to expand capacity in an existing DLBX deployment, verify the target chassis unit count matches the 5 RU height this rail provides.

For complete rack accessory builds, pair the DLBX-RR5 with appropriate 10-32 rack screws and cage nuts (sold separately). The 10-32 thread pattern is compatible with the overwhelming majority of commercial rack-mount equipment, including 1U switches, 1U audio processors, patch panels, and compact NVRs sized for drawer mounting. When planning a rack enclosure layout, account for the 20-inch depth in the drawer's weight and cable routing plan — equipment mounted at the rear of the rail will sit close to the chassis back panel when the drawer is closed.

Installers sourcing DLBX series components should reference Middle Atlantic's current DLBX product family documentation to confirm chassis-to-rail compatibility before ordering. For larger-scale Middle Atlantic rack builds, additional DLBX rails and drawer hardware are available as discrete components, allowing incremental expansion without full chassis replacement.

Frequently Asked Questions

Q: What enclosure series is the DLBX-RR5 designed for?

A: The DLBX-RR5 is designed exclusively for the Middle Atlantic DLBX series slide-out drawer enclosures. It is not a universal rack rail and should only be installed in DLBX chassis where the hole pattern and engagement geometry match.

Q: What thread type does the DLBX-RR5 use?

A: The DLBX-RR5 uses the 10-32 thread standard, which is the industry-standard thread for rack-mount equipment. Most commercial 1U and 2U rack gear is designed for 10-32 fasteners, so no adapters are required for standard rack-mount components.

Q: How deep is the DLBX-RR5 rack rail?

A: The rail is 20 inches (50.8 cm) deep, matching the full usable depth of the DLBX drawer chassis to ensure proper equipment support along the entire rail length.

Q: How many rack units does the DLBX-RR5 provide?

A: The DLBX-RR5 provides 5 rack units (5 RU) of usable height, corresponding to a usable height of 8.75 inches (22.2 cm).

Q: How many rails are included per package?

A: One rail is included per package (Package Count: 1). Order the quantity that matches your installation requirement.

Q: What is the shipping weight of the DLBX-RR5?

A: The DLBX-RR5 ships at 1.7 lbs (0.8 kg), adding minimal overhead to drawer load calculations.

The DLBX-RR5 is a single-purpose component — a 20-inch, 10-32 threaded steel rack rail for Middle Atlantic DLBX series slide-out drawers — and that specificity is exactly why it belongs on the shelf of any integrator running DLBX hardware in their rack builds. When a rail gets damaged or you're expanding a DLBX chassis for additional 10-32 equipment, ordering the matched OEM rail instead of a generic substitute eliminates the alignment headaches that come from mismatched tab geometry.

Technical Highlights:

• 20-inch rail depth: Spans the full DLBX drawer chassis depth (50.8 cm), distributing mounted equipment load evenly rather than cantilevering weight off front-panel fasteners alone — a real concern in mobile rack or frequently-accessed drawer installations.
• 5 RU / 8.75-inch usable height: Practical for a 1U NVR, a 1U managed switch, or a 2U patch panel segment inside the drawer — five units is the threshold where a slide-out drawer starts carrying genuinely useful rack density.
• 1.7 lb rail weight: Negligible relative to drawer load ratings — the rail adds almost nothing to the equation, keeping the full weight budget available for mounted equipment.

Deployment Considerations:

• Confirm your existing DLBX chassis unit count before ordering — the DLBX-RR5 is a 5 RU rail and must match the chassis height it installs into. Installing a mismatched RU count rail in a DLBX unit will leave mounting holes unaligned.
• Package Count is 1 (a single rail). Most slide-out drawer configurations require two rails for full equipment support — order accordingly rather than assuming pairs are included.

The DLBX-RR5 is the right stock item for integrators managing multi-rack DLBX deployments in broadcast, security operations, or AV control rooms where drawer hardware sees regular use and occasional rail replacement is a maintenance reality — not an emergency.
