Metal Line 101 is an anodized aluminum, recessed skirting board that is ideal for drywall. It is fitted to the unfinished wall by using specific adhesives before the final drywall is installed. The drywall or panel (max thickness 9/16" or 15mm), which covers the top of the skirting board, produces a recessed-type baseboard and is set into the wall. This skirting board delineates the perimeter of the room non-invasively with no protrusions.
