Safely seal off unused electrical boxes with a durable galvanized steel cover plate built to code standards. This is a 4-inch round electrical junction box cover plate with a 1/2-inch centre knockout. Made of galvanized steel, the plate has a mottled metallic grey appearance from the zinc coating that prevents rust and corrosion.
Product Facts:
- 4-inch round galvanized steel junction box cover plate
- Mottled metallic grey finish from zinc coating
- Keyhole-shaped mounting slot on one side, open-ended slot on other side
- Centre circular knockout (1/2 inch)
- Thin, approximately 1/16 inch thick
Perfect for:
- It features a keyhole-shaped mounting slot on one side for easy installation — a screw can be partially driven in, then the plate slid into position and tightened — and an open-ended slot on the opposite side for the second mounting screw
- The centre knockout can be punched out with a screwdriver or hammer if a wire or threaded rod needs to pass through the plate
Electricians use these for finishing rough-in work, and DIY homeowners use them when capping off old electrical points during renovations.
