Buying Guide
- Compatibility: Check center-to-center (CTC) measurements and hole spacing to match existing sash rails and meeting rails. Match the lock or lift to the window type (single/double hung or casement).
- Finish and style: Choose antique brass or brushed antique finishes to align with your hardware palette and the home’s era. A genuine brass finish can patina gracefully over time.
- Material and durability: Diecast and forged brass options offer higher durability for frequent use and weather exposure. Consider stainless steel options for corrosive environments.
- Security features: Cam-action latches and locking mechanisms provide improved security. Some units include keepers or mounting hardware; verify what’s included before purchasing.
- Quantity and installation: Bulk packs (like 4-pack or 8-pack) are convenient for multiple windows or future replacements. Ensure you have the required screws and mounting hardware compatible with your frame.
- Window type considerations: Some locks are tailored for wooden frames, while others suit vinyl or metal windows. Confirm whether the product is designed for your specific sash profile.
- Ease of replacement: Look for standard screw patterns and straightforward installation to minimize modification to existing trim or frame.
- Aesthetics vs. function: While preserving period appearance, prioritize secure operation and longevity to ensure long-term performance and safety.
