Steel City 664 Floor Box Cover
The Steel City 664-CST-SW-GRY is a single-gang floor box cover made from polycarbonate. It is designed to fit 664 series floor boxes and provides a protective lid for electrical or low-voltage connections. The gray finish suits commercial and residential interiors.

UL E2969 Listed Safety Compliance
This cover carries UL listing E2969, confirming it meets recognised safety standards for floor box accessories. Polycarbonate construction resists impact and heat during normal service. The material does not conduct electricity, reducing shock risk. No moving parts or motors mean silent operation and zero power draw.

The rectangular cover measures 8 1/4 inches by 5 1/4 inches with a 4-inch height. Its rigid polycarbonate body withstands foot traffic and cleaning equipment. The single-gang opening accepts standard device plates or inserts. Mounting aligns directly with 664 series boxes for a secure, flush fit.

Questions about this item
How do you install the Steel City 664-CST-SW-GRY cover onto a 664 series floor box, and what step is often missed?
Align the rectangular polycarbonate cover with the 664 series box opening, then secure it using the supplied screws; the step often missed is tightening the screws evenly to keep the cover flush with the floor surface.
What maintenance or replacement will the gray polycarbonate cover need over time?
Inspect the cover periodically for cracks, discolouration or loose screws; replace the cover if the polycarbonate becomes brittle or damaged, and re-tighten fasteners whenever they work loose.
What limit appears first when the cover is subjected to sustained foot traffic and cleaning?
The polycarbonate material will show surface wear and potential stress cracking before the UL E2969 listing is compromised, so monitor for visible damage as the primary indicator.
