Buying Guide for Sash Locks for Windows
Understanding Sash Locks
When I first started researching sash locks, I learned they are essential for securing double-hung windows. These locks hold the sash in place and prevent it from being opened from the outside. This gives me peace of mind, especially in a home with children or in an area prone to break-ins.

I discovered that there are several types of sash locks available. The most common types include cam locks, sliding locks, and key-operated locks. Cam locks are simple and effective, while sliding locks offer a bit more security. Key-operated locks provide additional protection, which is something I consider when evaluating my home’s security needs.
Material Considerations
When I began comparing sash locks, the material caught my attention. Sash locks can be made from materials like brass, stainless steel, or aluminum.
