- Window type compatibility: Verify whether the lock fits single or double hung configurations and if it accommodates wood, vinyl, or aluminum frames.
- Center-to-center mounting: Check hole spacing (e.g., 2-1/16 in, 2-1/4 in) to ensure proper alignment with existing mounting holes.
- Locking mechanism: Cam-action locks provide strong gripping action that tightens the rails, improving seal and security; confirm the mechanism is easy to operate for all household members.
- Material durability: Diecast and zinc alloy housings resist wear and corrosion; durable screws and keepers minimize maintenance over time.
- Installation quantity: Assess whether you need a single lock replacement or a bulk set for multiple windows; kits with screws simplify installation.
- Final aesthetics: White or enamel finishes blend with common window frames; consider compatibility with trim and interior décor.
- Security considerations: Cam-action hooks and reinforced latches deter tampering and improve overall home safety.
- Maintenance and replacement: For older windows, choose models with readily available replacements and compatible keepers.
