Frontier20 Montauk Black Grip Stair Tread Bullnose Slate Look Porcelain Moldings 12x48

Frontier20 Montauk Black, 12x48, a porcelain Grip Stair Tread Bullnose with a slate face. Frontier20 is the 20 mm outdoor programme, thick enough to be laid dry on gravel, sand or pedestals.

Natural slate sheds thin layers over time in a busy room; the porcelain face stays as it is. This is the walking surface of a step, made with a finished front edge rather than a cut one.

The body is 20 mm and the edges are rectified, so it lays with a tight grout joint. The surface is matte. One box covers 3.2 sq ft, 1 piece.

It is produced to order rather than pulled from stock, which is worth planning for early in a job. Production is domestic, from the Mount Pleasant, Tennessee plant.
