Product Description

The ABB RF2BB is a roof flashing plate designed to seal around 2-inch conduit penetrations through roofing assemblies. It provides a weather-resistant barrier at the point where conduit exits or enters a roof surface, protecting the opening from moisture intrusion and environmental exposure. Electricians and contractors install this plate during conduit runs that transition from interior or underground pathways up through a roof deck. The RF2BB is a straightforward, single-purpose fitting that keeps the roof penetration clean and properly sealed after conduit is in place.

This flashing plate is used wherever a 2-inch conduit passes through a roof surface on residential or light commercial installations. Typical applications include service entrance conduit runs, rooftop HVAC disconnect feeds, photovoltaic system wiring, and similar above-deck conduit work. It seats flat against the roofing material around the conduit, allowing the installer to complete the seal with appropriate roofing compound or caulk as required by local code and roofing system type.

Installation Notes

Installation is typically performed by a licensed electrician in accordance with applicable NEC requirements for conduit penetrations. Secure the flashing plate against the roof surface before finalizing the conduit run, and seal the perimeter with a roofing-compatible sealant per the roofing manufacturer and local code requirements. Ensure the roof surface is clean and dry before seating the plate to achieve a proper seal.
