If you’re looking for a door or window locking solution that combines classic elegance with dependable security, a Cremone bolt is an excellent choice. Originally designed for French windows and traditional doors, Cremone bolts have become a popular option in both residential and commercial properties thanks to their stylish appearance and practical functionality. They use a central handle to operate two vertical rods simultaneously, locking securely into the top and bottom of the frame with a single movement.

Whether you’re renovating a heritage property or adding character to a modern home, choosing the right Cremone bolt can improve both security and aesthetics.

What Is a Cremone Bolt?

A Cremone bolt is a surface-mounted locking mechanism that features a central handle or knob connected to vertical rods. When the handle is turned, the rods move simultaneously into sockets at the top and bottom of the door or window frame, creating a secure locking system. Unlike standard tower bolts, a Cremone bolt locks both ends with one simple action.
