Middle Atlantic 1.39 IN Device Plate #1 - CRFB-SR1-1

Middle Atlantic CRFB-SR1-1 1.39-Inch Rack Enclosure Device Plate

Overview

The CRFB-SR1-1 is a 1.39-inch device plate designed for Middle Atlantic CRFB-series rack enclosures. Device plates in this series serve a specific structural role: they fill a defined opening in the enclosure panel, providing a finished, flush-mount surface for pass-through connectors, grommets, or blank coverage where no active device is installed. If you are building out a CRFB enclosure and need to close off an unused port opening or mount a low-profile connector panel at the 1.39-inch form factor, this is the part to specify.

Compatibility

The CRFB-SR1-1 is matched to Middle Atlantic's Middle Atlantic CRFB-series rack enclosures. The "CRFB-SR" designation identifies it as a slide-out rack blank or device plate within that enclosure family. Confirm your specific CRFB enclosure model accepts the SR1 plate position before ordering — Middle Atlantic enclosures often have numbered plate positions (SR1, SR2, SR3) that correspond to distinct cutout locations and dimensions within the same chassis. Mixing SR-position plates across positions will result in fitment failures. This plate is not a universal blank and is not cross-compatible with Middle Atlantic's other rack enclosure lines (such as the CABS or BGR families) without verification against your enclosure's plate map.

Installation Notes

Device plates in the CRFB-SR series are panel-mount components — no rack unit height is consumed independently; the plate installs into the enclosure's designated cutout. Verify the 1.39-inch dimension matches your enclosure's SR1 opening before ordering. For security integrators building out equipment racks for surveillance or AV control rooms, confirm the full plate complement for your CRFB chassis at time of order to avoid gaps in panel coverage that require a return shipment.
