What it is and who it fits

This 4 inch square floor drain cover is made from 304 stainless steel with a black finish. It uses a screw-in mounting pattern with hole centres at 85.7 mm and an outside dimension of 101.6 mm. The package includes both machine and self-tapping stainless screws for installation.

Thickness and drainage flow

The cover is 1.8 mm thick to resist deformation during daily use. Drainage holes measure about .4 inch (10 mm) in diameter to maintain a high flow rate and reduce clogging in showers, kitchens or balcony floors.

Sustained wet environments

304 stainless steel provides corrosion resistance for continuous exposure to water and cleaning agents. The screw-in design keeps the grate secure under foot traffic without the movement common to snap-in types.

Questions about this item

How do I install the 4-inch screw-in square drain cover and what measurement mistake should I avoid?

Remove the old cover, align the new cover's screw holes at 85.7 mm centre-to-centre, and fasten with the supplied machine or self-tapping screws; measure both the 101.6 mm outer square and the screw spacing before purchasing.

What maintenance will the 304 stainless steel cover need over time?

Periodically lift the cover to clear hair and debris from the 10 mm drainage holes; the 1.8 mm thick 304 stainless steel resists corrosion, so no finish maintenance is required beyond routine cleaning.

What is the first limitation that appears during heavy, continuous water flow?

The 10 mm diameter drainage holes set the maximum flow rate; sustained high-volume water can back up if the holes cannot pass water fast enough.
