11/16" x 1-1/8" Back Band (8313PRF) – Primed Finger Jointed Moulding is a decorative trim accent designed to add depth and dimension to door and window casing assemblies. Installed along the outer edge of existing casing, this back band creates a built-up, layered look that enhances architectural detail without replacing the primary trim. The 1-1/8" face width provides subtle projection and clean shadow lines, while the 11/16" thickness ensures durability and secure fastening. Manufactured from primed finger jointed material for improved straightness and consistency, the 8313PRF arrives paint-ready to streamline installation in both new construction and remodeling projects.
