Installers needing a brass cover for P64 boxes

Electricians finishing a floor-box rough-in will find the correct gang count and conduit size here. Projects that require a different gang configuration, a non-brass finish, or a cover not compatible with P64 plates should look elsewhere.

Brass construction in daily service

Brass resists corrosion and holds its threads during repeated cover removal. The material withstands foot traffic and cleaning moisture without rusting. TSCA compliance confirms the alloy meets regulated substance limits for installed hardware.
