The ARLINGTON FBC42252W is a non-metallic blank cover designed to close off and protect electrical boxes where no device or wiring connection is present. Finished in white, it provides a clean, flush appearance on completed installations. The cover is lightweight at 0.13 pounds and is suited for use with standard non-metallic (NM) electrical boxes. Electricians and electrical contractors install this type of blank cover as a code-required closure on unused junction and device boxes in residential and light commercial wiring systems.
This blank cover is appropriate for residential new construction, renovation work, and service calls where an electrical box must be closed but no receptacle, switch, or fixture is being installed. It is commonly used in situations where future access to the box may be needed, or where wiring has been terminated and capped inside a box that will remain inactive. The white finish blends with standard wall and ceiling surfaces.
Designed as an OEM-style replacement and standard fitment blank cover for non-metallic electrical device boxes in residential and light commercial applications.
Installation is performed by a licensed electrician or qualified electrical contractor. Always de-energize the circuit at the breaker panel and verify the absence of voltage before working inside any electrical box. Blank covers on junction boxes must remain accessible per NEC requirements and should not be concealed behind finished surfaces unless the box is properly listed for that application. Fasten the cover securely using the hardware appropriate for the box type.
