The Chamfer Round profile is much like the standard chamfer design but features a slightly rounded top edge. It's manufactured using premium moisture resistant MDF meaning imperfections such and knots, cracks and splintering are non-existent.

Note that the moulded section is approximately 25mm (from where the design starts to where it finishes) and does not change regardless of the width you choose. This product is 70mm in width, 18mm in thickness and 2440mm in length. It has a primed (white) finish.
