The Andersen Sash Lock Stone LH serves as a direct OEM replacement for vintage Andersen windows with a 3-hole installation pattern, making it the right choice for contractors maintaining Montana homes built during the 1970s-1990s construction boom. Part numbers 1351408, 7191-32, and A-1351408 replace the legacy 0565708-0565712 series, eliminating the guesswork when ordering replacement hardware for aged window systems.
Compatibility Timeline and Installation
This left-hand sash lock fits Andersen 400 Series Casement and Awning Windows manufactured from 1966-1995, Wood Casement Windows from 1974-1989, and Perma-Shield models from 1966-1995. That covers nearly three decades of Andersen’s most popular window lines — exactly what contractors encounter in Montana’s existing housing stock.
The real improvement comes in the installation. The current 3-screw hole pattern replaces the earlier 4-screw version, saving time on every window. Installation takes approximately 5 minutes with just a screwdriver — remove the old screws, align the new lock with existing holes, and secure with the included screws. No drilling. No modifications.
The kit includes the left-hand stone sash lock, matching keeper, and mounting screws. Everything arrives ready to install. For right-hand applications, order part number 1351410 instead.

Frequently Asked Questions
How do I determine if I need left-hand or right-hand hardware? Handedness is determined by lock location when viewed from the interior. Stand inside looking at the closed window. If the lock sits on your left, order the LH version (1351408). Lock on the right requires the RH version (1351410).
Will this work on windows manufactured before 1966? No. This lock specifically fits Andersen 400 Series Casement/Awning (1966-1995), Wood Casement (1974-1989), and Perma-Shield models (1966-1995). Earlier windows use different mounting patterns.
What tools are required for installation? Only a screwdriver is needed. The 3-hole design aligns with existing mounting points from 4-hole versions, so no drilling is required.
Are mounting screws included? Yes. The kit includes the left-hand stone sash lock, matching keeper, and mounting screws. No additional hardware purchases needed.
