Frontier20 Limestone Riser Look Porcelain Moldings 8x24

Frontier20 Limestone, 8x24, a porcelain Riser with a limestone face. Frontier20 is the 20 mm outdoor programme, thick enough to be laid dry on gravel, sand or pedestals.

Real limestone is porous enough to stain and needs sealing on install; the porcelain version skips both. This is the upright face of a step, sized to sit under the tread and finish the flight.

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 2.58 sq ft, 2 pieces.

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.
