SEAMLESS REPLACEMENT: Works perfectly with 200 Series Perma-Shield Narroline (1968 to Present) and 400 Series Tilt-Wash Double-Hung windows (1994 to Present). The screw holes align with the original locks, making them easy to replace. UPGRADED METAL CONSTRUCTION: Crafted from heavy-duty zinc alloy, this traditional sash lock kit offers maximum security and weather resistance. It replaces the flimsy OEM plastic parts (like 1630029) with a permanent, unbreakable solution.
UPGRADED ANTI-SCRATCH DESIGN: The window lock parts built-in protective vinyl insert. This minimizes metal-on-metal friction, avoiding grinding away paint during daily use, ensuring smooth locking action while keeping the finish looking brand new for years. COMPLETE KIT WITH PAINTED SCREWS: This kit includes 1 sash lock, 1 keeper, and 4 color-matched self-tapping screws. The painted screw heads blend seamlessly into the lock body, restoring your window's elegant appearance instantly.
