Roberts Designs Square Edge Trim Black 12mm x 3m Aluminium Box Tiling Angle

A square box profile rather than an L-angle: the visible face is a flat square edge, which is the detail specifiers ask for on rectified and large format tile. Roberts Designs, black anodised aluminium, 12mm to suit the tile and adhesive bed, 3 metre length. Matching square-edge corner pieces are made for it, and the size run is 6mm to 15mm if the bed comes up thicker.
