These mechanisms, typically found at a major home improvement retailer, secure the movable part of a window to the frame. They prevent unauthorized entry and ensure the window remains closed against external elements. A common example includes a cam-action lock, which engages when the lever is turned, drawing the sash tightly against the window frame.
Properly functioning securing devices contribute significantly to residential security and energy efficiency. By maintaining a tight seal, they reduce drafts and minimize heat loss during colder months, contributing to lower energy costs. Historically, less sophisticated methods were employed, but modern hardware offers enhanced durability and resistance to forced entry, providing homeowners with a higher degree of protection.
