The Andersen Sash Lock Stone LH solves a specific problem for contractors maintaining vintage Andersen windows — replacing worn-out locks on casement and awning windows built between 1966 and 1995. This OEM replacement fits 400 Series Casement/Awning windows (1966-1995) and Perma-Shield models from the same era, using a simplified installation that takes about 5 minutes.
Compatibility and Installation
The lock has part numbers 1351408, 7191-32, and A-1351408, replacing legacy part numbers 0565708 through 0565712. The critical detail contractors need: this is a left-hand (LH) lock, determined by lock location when viewed from the interior. Get the handedness wrong, and you’ll be returning it for part 1351410, the right-hand version.
The installation efficiency makes this lock worth stocking on service trucks. The new 3-screw hole pattern replaces the older 4-screw version, meaning less drilling and faster installations. Installation steps are straightforward: identify the lock handing from interior, remove existing screws from old lock and keeper, align new sash lock with existing holes, and install new screws (included). Total time: approximately 5 minutes.
