Frontier20 Dune Riser Limestone Look Porcelain Moldings 12x48

This is the Frontier20 Dune Riser, 12x48 in a limestone face. Frontier20 is the 20 mm outdoor programme, thick enough to be laid dry on gravel, sand or pedestals.

The appeal of limestone is that it does not draw attention to itself, which is what makes it work across a large floor. 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, 1 piece.

It is made in the United States, at Landmark's Mount Pleasant plant in Tennessee.
