Window Spring Bolt

A window spring bolt is a type of locking mechanism that is used to secure a window in place at different elevations. It typically consists of a metal spring bolt that is attached to the window sash that engages into the apposing sash to keep the window in predetermined amounts of opening.

When the window is closed, the bolt can be extended to engage with apposing drilled hole, holding the window firmly in place and preventing it from being opened from the outside. The spring-loaded bolt allows the bolt to be easily released when the window needs to be opened.

Window spring bolts are commonly used in residential and commercial buildings as an additional security measure to help prevent break-ins or unauthorized access. They can be installed on various types of windows, including sliding windows, double-hung windows. Window spring bolts can also be uses to hold wood framed screens into the window frame.
