The DS255 Sliding Window Limiter Lock is designed for use on residential aluminium sliding windows.

The DS255 sliding window limiter lock is designed to be easily installed into the top rail of the sliding window.

Once installed the device restricts the window from opening at a distance pre-determined by the installer.

An innovative feature of the DS255 is the key operated removable body which can be easily separated from the window for emergency egress and cleaning purposes.
