1-Piece Square Outside Corner 5/16″ Trim
5/16″ Trim System½″ step shadow line
An extruded aluminum trim system for fiber cement, vinyl, engineered wood and natural wood cladding. Every profile is blind nailed, so no fastener shows and there is nothing to caulk at the joint.
Profiles listed from the manufacturer's current profile legend. Stock, anodized and primed finishes, or any colour through the ColorMatch® program. Confirm finish availability and lead time with the order desk before release.

No profiles match that combination. Clear a filter, or ask the order desk — the mill runs specials that are not on the legend.
The panel trim system, sized for 5/16″ fiber cement sheet and panel from every major manufacturer. Replaces board-and-batten with a blind-nailed reveal. 10′ lengths.
