Frontier20 Indiana Buff Select Riser Limestone Look Porcelain Moldings 12x48

This is the Frontier20 Indiana Buff Select 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. A riser is the vertical face of a step, the piece you see when you look at a flight from the front.

The body is 20 mm and the edges are rectified, so it lays with a tight grout joint. The surface is matte. It is sold by the box, 2.58 sq ft per box and 1 piece in it.

This one is made to order, so allow production time rather than treating it as a shelf item. It is made in the United States, at Landmark's Mount Pleasant plant in Tennessee.
