Window latches are small devices used to secure windows in a closed position. They help prevent the window from being opened unintentionally, providing safety and security for homes and buildings. Latches come in various designs, including sliding, hook, and cam types, and are typically made from materials like metal or plastic. In addition to security, window latches also contribute to energy efficiency by keeping windows tightly sealed. This helps to reduce drafts and maintain indoor temperatures. Properly functioning latches are essential for the overall performance of windows, ensuring they operate smoothly and effectively.
