The Sally Interior Plaster Light Cove Moulding

Starting at $49.79 per 8' Length ($6.22/Ft)

The Sally Light Cove is a stately interior plaster-coated profile specifically engineered to combine timeless architectural detail with modern LED integration. Designed to coordinate flawlessly with the Sally Beam and Crown, this profile features a specialized mounting geometry that creates a discreet trough for LED strip lighting. This allows for a seamless "halo" illumination effect, washing the ceiling in soft, indirect light while keeping the source entirely hidden from view.

This profile can be custom modified to suit site needs, offering a refined one-piece fabrication that eliminates the need for complex, site-built "light pockets" or multi-member wood assemblies. The signature ultra-smooth plaster coating delivers a sophisticated, monolithic masonry appearance that remains dimensionally stable and will not warp or crack from the heat of LED components, ensuring a permanent finish for the life of the project.

Complete Interior Moulding System Line
