Middle Atlantic RFB4 Brkt W/low Profile B - RFB4-LPB

Middle Atlantic RFB4-LPB Rack Filler Bracket with Low Profile Bar

Overview

The Middle Atlantic RFB4-LPB is a rack filler bracket paired with a low profile bar, designed to close open rack unit space and provide a clean, professional finish in equipment enclosures. The RFB4-LPB is the right choice when you need to fill unused rack units in a rack enclosure while maintaining a low-profile front clearance — useful in shallow-depth racks or anywhere rear cable management space is at a premium. Blank filler panels like this one also improve airflow discipline by blocking bypass air that would otherwise short-circuit front-to-back cooling in populated racks.

Compatibility

Designed for use with Middle Atlantic rack enclosures and open-frame racks built to standard EIA-310 19-inch rack rail spacing. The low profile bar variant is suited for installations where standard-depth brackets would obstruct cable trays, PDUs, or other rear-mounted hardware. Confirm your rack's rail depth and filler panel bay dimensions against Middle Atlantic's rack enclosure specifications before ordering — while 19-inch EIA-310 rail spacing is universal, filler panel flange depth and mounting hole pattern can vary between product families. Compatible with Middle Atlantic's RFB series filler panel ecosystem for consistent panel aesthetics across mixed-population racks in AV and security equipment rooms.
