Middle Atlantic Legrand-middle Atlantic RCK Accories RFR EMC Rear Rail 20SP - RFR-ERRK-20

Middle Atlantic RFR-ERRK-20 Extra Rear Rack Rail Kit — 20RU

Overview

The RFR-ERRK-20 is a rear rack rail kit sized for 20-rack-unit RFR-series slide-out rack frames. If you're mounting equipment that requires rear rail support — rackmount UPS units, patch panels, cable managers, or any component that ships with rear-mount ears — this kit gives you the additional anchoring point your RFR chassis doesn't include out of the box. At 35 inches of usable height within a 20-inch depth envelope, the RFR-ERRK-20 matches the physical footprint of the RFR-2020 and related 20RU RFR frames exactly. The 10-32 tapped rail accepts standard 10-32 cage nuts and rack screws, so you're working with the same fastener spec as the front rails — no sourcing a separate hardware kit.

Compatibility

Designed specifically for the Middle Atlantic RFR Base Series — compatible with 20RU slide-out rack accessories and enclosures in the RFR product family. Confirm your chassis is a 20RU RFR-series unit before ordering; the ERRK kit is depth- and height-matched to that frame only. The 20-inch depth (50.8 cm) matches the standard RFR cabinet interior, and the 10-32 rail type is consistent with rack infrastructure across the Middle Atlantic lineup. Not compatible with RFR frames of different RU counts (e.g., 12RU or 16RU variants require their corresponding ERRK kit). Review your rack planning requirements before selecting rail depth and unit count.
