Molding strips that crack when you nail them or don't stay put once installed — you end up callbacks and touch-up paint on finish trim work that should have been clean. These fiberglass strips give you the flexibility to shape around arches and irregular openings without the splitting risk of wood. Fiberglass construction resists rot, moisture, and temperature swings better than wood — the material doesn't expand and contract with seasonal humidity the way wood does. Strips cover the gap between decorative molding and rough framing, bridging the transition cleanly on historic remodels and new construction alike. Standard on the finish trim inventory of cabinetmakers and remodelers across northeast Nebraska and northwest Iowa — the strip that handles the odd-size gaps that Stocked at Crofton Lumber and Akron Lumber.
