Centaur P4BC – Frequently Asked Questions

1) Will the Centaur P4BC blank cover fit a standard 4x4 non-metallic box?
Yes. The P4BC is a 4 x 4 inch blank cover made for standard 4-inch square electrical boxes, and it mounts directly to the box face rather than needing an adapter ring. It measures 4 inches wide by 4 inches high with a 4.7 inch overall length dimension, so it covers the box opening and lands on the mounting ears of a non-metallic box.
2) Is this PVC cover fire rated, and does it carry a listing I can show an inspector?
The P4BC is ETL listed and carries a 2-hour fire rating, which is what an electrical inspector or an institutional facility reviewer will want to see on a blanked-off box in a rated assembly.
3) Can I use this cover on a box where insulation or a vapor seal is required?
No. The P4BC is a non-insulated cover. It closes and protects an unused box, but it is not an insulated or air-sealing product, so if your detail calls for an insulated box cover this is the wrong part.
4) Is this a blank cover or does it have device openings?
It is a blank cover, no device cutouts. Use it where a 4x4 box is installed but no receptacle, switch, or plate is going in, including boxes left for future use or junction boxes that must stay accessible but closed.
5) How many covers come in a box of Centaur P4BC?
They ship 50 per box, which is why they suit a contractor rough-in or an MRO stockroom standardizing on one blank cover across a building rather than a one-off repair. Each cover weighs 0.18 lb.
6) What color is the P4BC cover, and will it match my existing PVC boxes?
Gray PVC, which matches the standard gray non-metallic boxes and PVC raceway used on commercial work, so blanked openings stay visually consistent with the rest of the run.
