Waffle Grid 4-packIntroducing The Waffle Grid, an interconnecting grid which allows the user to configure the shape of their work table. Through its unique design, you can configure around a corner, as a connecting backsplash or even randomly turn up individual grids to have a smooth area amid a pocketed area. You can even see through it for angle patterns. Made of high impact Lexan, the surface of the 1 2 inch pockets is rounded smooth to allow your glass to glide.
