Middle Atlantic 26in. in. SLIM5 BOT RUNNER SET - 5-RS26

Middle Atlantic 5-RS26 26-Inch SLIM5 Bottom Runner Set

The Middle Atlantic 5-RS26 is a purpose-built bottom runner set designed for SLIM5 rack enclosures, providing the structural foundation that keeps rack-mounted equipment seated, stable, and properly aligned. At 26 inches deep, the 5-RS26 (often searched as 5 RS26) matches the internal depth of compatible SLIM5 enclosures — which matters because a runner set that doesn't match enclosure depth won't support equipment evenly, creating stress points on chassis rails and connector backplanes. If you're specifying or refreshing a Middle Atlantic rack system, this is the correct replacement or supplemental runner kit for the 26-inch SLIM5 platform.

Overview

Bottom runners in a rack enclosure do one job: give rack-mounted gear a solid, even resting surface along the full chassis depth. The 5-RS26 spans 26 inches (66 cm) front-to-back, matching the internal travel distance of SLIM5 enclosures at this depth class. The runner profile is low-profile at 0.25 inches (0.6 cm) tall — shallow enough to fit within standard rack U-space without consuming usable rack height. Width is 1.5 inches (3.8 cm), consistent with standard runner channel geometry for the SLIM5 series. Shipping weight is 1.5 lbs (0.7 kg), so the set is light enough to stage and install without additional handling equipment. For integrators building out rack enclosure systems, runner sets like this are a routine but important line item — field-improvised substitutes introduce uneven load distribution and increase the risk of equipment movement during transport or installation.

Key Features

• 26-Inch Depth Match (66 cm): The runner length is dimensioned to the SLIM5 26-inch enclosure interior — equipment slides in and rests along the full depth rather than cantilevering off a shorter runner. Mismatched depth is one of the most common causes of chassis flex in populated racks.
• 0.25-Inch Low-Profile Height: At just 0.25 inches (0.6 cm) tall, the runner set doesn't eat into usable rack unit space. In dense deployments where every U matters — NVR shelves, patch panels, managed PoE switches — keeping accessory hardware thin preserves layout flexibility.
• 1.5-Inch Channel Width: The 1.5-inch (3.8 cm) runner width is designed to the SLIM5 channel standard. Substituting off-spec runners risks lateral play in the chassis, which compounds vibration effects in environments with HVAC turbulence or nearby mechanical equipment.
• 1.5 lb Shipping Weight: The full set ships at 1.5 lbs (0.7 kg). This is relevant for integrators calculating freight on multi-enclosure orders or staging kits across sites — runner sets are easy to overlook in BOM planning until a rack arrives on-site without them.
• Factory-New Genuine Part: Sourced as a genuine Middle Atlantic component — not an aftermarket substitute. Runner geometry tolerances matter more than they appear; a few thousandths of an inch in channel width affects slide resistance and long-term wear on equipment rails.

Integration & Compatibility

The 5-RS26 is designed for the Middle Atlantic SLIM5 enclosure series at the 26-inch depth specification. Before ordering, confirm your enclosure model's internal depth and runner channel dimensions against the 26-inch / 1.5-inch width spec. If your enclosure is a different depth variant in the SLIM5 line, Middle Atlantic offers runner sets sized to match — using the wrong depth runner in an enclosure is a fitment problem you'll find immediately on installation, not after the fact. This runner set is a hardware component with no electrical connections, VMS dependencies, or network integration requirements. It pairs with any rack-mounted gear — network video recorders, UPS units, AV equipment — as long as the enclosure is the correct SLIM5 26-inch platform.

Frequently Asked Questions

Q: What enclosure series is the 5-RS26 designed for?

A: The 5-RS26 is designed for the Middle Atlantic SLIM5 enclosure series. It is sized to the 26-inch depth variant of that line. Verify your enclosure's internal depth before ordering — different depth variants require their corresponding runner set.

Q: Will the 5-RS26 fit a standard 19-inch rack that isn't a SLIM5?

A: The 5-RS26 is a Middle Atlantic SLIM5-specific component. Its 1.5-inch channel width and 26-inch depth are dimensioned to the SLIM5 enclosure interior. Compatibility with other rack brands or series is not supported by the available evidence — check Middle Atlantic's enclosure compatibility documentation for your specific rack model before ordering.

Q: How much does the 5-RS26 weigh?

A: The shipping weight is 1.5 lbs (0.7 kg) for the full runner set.

Q: Does the 5-RS26 consume any rack unit (U) space?

A: At 0.25 inches (0.6 cm) tall, the runner set has a very low profile and is designed to fit within the enclosure's base without consuming standard rack unit height.

Q: What are the exact dimensions of the 5-RS26?

A: Depth: 26 in (66 cm). Height: 0.25 in (0.6 cm). Width: 1.5 in (3.8 cm). Shipping weight: 1.5 lbs (0.7 kg).

The 5-RS26 is the kind of part that stops a rack build cold when it's missing from the BOM. At 26 inches deep and 1.5 inches wide, this runner set is dimensioned specifically to the SLIM5 enclosure interior — and that precision matters more than it looks on a spec sheet. I've seen integrators substitute a shorter runner 'temporarily' and then find chassis flex issues six months later when the equipment starts showing connector wear.

Technical Highlights:

• 26-Inch Depth (66 cm): Full-depth runner coverage means the chassis rests along its entire bottom surface — no overhang, no cantilevering, no uneven load on the front rails.
• 0.25-Inch Profile Height: Thin enough to install inside the enclosure base without affecting usable U-space. In a fully-populated SLIM5 build, that clearance is not something you want to discover you've lost after the equipment is in.
• 1.5-Inch Channel Width: Matched to the SLIM5 channel standard. Off-spec runners introduce lateral slop that shows up as vibration noise and accelerated rail wear — both avoidable with the correct part.

Deployment Considerations:

• Verify your SLIM5 enclosure's internal depth is the 26-inch variant before ordering — Middle Atlantic runner sets are depth-specific, and the wrong size won't fit correctly regardless of how close the dimensions appear.
• At 1.5 lbs (0.7 kg) shipping weight, this is a lightweight add to any rack hardware order, but it's easy to omit from initial BOM drafts — flag it as a required line item when specifying any SLIM5 26-inch enclosure build.

The 5-RS26 is the right call for any integrator commissioning or refreshing a SLIM5 26-inch rack enclosure in a security operations center, network closet, or AV equipment room where equipment stability and correct fitment are non-negotiable.
