A spring catch with a back offset is a type of hardware commonly used in windows to hold the sash in place. It consists of a spring-loaded mechanism that engages with a strike plate mounted on the window frame. The back offset feature of the catch allows it to be installed on a recessed or deep-set window frame, providing a more secure and flush fit. The catch operates by pressing down on a lever or button, which compresses the internal spring and disengages the catch from the strike plate. This allows the window to be opened and closed as needed. When the lever is released, the spring snaps back into place, re-engaging the catch with the strike plate and holding the window securely in place. Spring catches with back offsets are easy to install and require minimal maintenance. They are an excellent choice for windows that require a secure locking mechanism, such as those located on the ground floor or in high traffic areas. Their simple design and reliable operation make them a popular choice for both residential and commercial applications. This Spring Catch features a durable, White Bronze construction. Spring Catches sold individually, Strike Plate/Keeper and Hardware Not Included.
