Rockwood LV-IY Inverted Y Steel Door Louver | 50% Free Air Flow High-Privacy Vent
The Rockwood LV-IY Steel Door Louver is a heavy-duty architectural ventilation solution engineered for both 1-3/4" wood and hollow metal doors. Featuring a specialized inverted "Y" blade design, this louver provides a generous 50% free air flow while maintaining superior privacy and sight-proof security. It serves as a definitive solution for door restoration, adding a professional mitered-frame finish to commercial, industrial, and institutional openings.
Constructed with an 18-gauge galvannealed steel frame, the LV-IY is a critical solution for door security and long-term durability. The precision-mitered frame securely locks the grille assembly in place, offering a flush, clean appearance on both sides of the door. This unit is an essential component for any solution for door surface repair, as the overlapping frame effectively conceals rough cutout edges on 1-3/4" thick doors, providing a seamless architectural look.
