The RACO 778 is a 4 in. square electrical box cover built for 2-device applications where extra interior clearance is needed.

Formed through drawn construction for a consistent one-piece fit, the 778 is cULus Listed, making it a dependable choice for a code-compliant finish plate on standard 4 in. square boxes in both new construction and renovation wiring projects. The 778 is well suited for electricians and contractors who need a reliable, ready-to-install cover for two-device box configurations in both commercial and residential settings.
Key Features
- Trade Size: 4 in. square cover sized to fit standard 4 in. square electrical boxes commonly used in branch-circuit wiring.

- 1/2 in. Raised Profile: The raised design adds extra interior depth compared to a flat cover, giving device bodies and wire connections more room inside the box.
- Drawn Construction: Formed through a drawn manufacturing process rather than welded, producing a one-piece cover with a consistent, uniform fit and no weld seams to work around during installation.
