Middle Atlantic RFR-ERRK-24 Extra Rear Rack Rail Kit for RFR Series

Overview

The RFR-ERRK-24 is a 24-space (24RU) extra rear rack rail kit designed for Middle Atlantic RFR-series slide-out rack enclosures. If your RFR chassis is populated with equipment that requires four-post support — think heavy amplifiers, dense patch panels, or AV processors with rear-rail mounting tabs — this kit delivers the missing rear anchor point without replacing the enclosure. At 4 lbs shipped and 20 inches of depth, the hardware is sized to match the RFR footprint exactly. The RFR-ERRK-24 ships as a single-unit package (Package Qty: 1), ready to drop into an existing rack enclosure installation.

Compatibility

Designed specifically for the Middle Atlantic RFR Base Series — the RFR family of slide-out rack enclosures. The 24RU (42 in / 106.7 cm usable height) configuration matches 24-space RFR chassis variants. Rail threading is 10-32, the standard tapped-rail format used throughout the RFR line, so existing rack accessories and cage-nut hardware already on hand will fit without adapter hardware. This kit is not designed for EIA square-hole or M6 metric rail systems — confirm your RFR chassis uses 10-32 tapped rails before ordering.

Installation Notes

The rear rail mounts inside the RFR enclosure at a depth of 20 inches (50.8 cm) — verify your enclosure's internal depth accommodates this before installation. The 10-32 thread pattern requires standard 10-32 rack screws; no cage nuts are needed. Confirm the installed equipment's rear-rail hole pattern aligns with 10-32 tapped spacing before committing deep-rack gear to this configuration. For rack planning in AV or security head-end closets, factor the added rear rail into your cable management layout — rear-rail-mounted gear will reduce the clearance behind equipment for cable routing.
