These fittings prevent a window from opening beyond 100mm (until they are manually overridden) and are particularly useful for upstairs bathrooms and bedrooms.

There are alternative solutions to these limit stops when the window is required to only ever open to a set dimension. Extended cover strip at the sides act as length stops to prevent windows being opened beyond the desired position, in place of these travel restrictors.

Limit stops are available colour suited to all other furniture in a variety of colours and are always fitted in pairs to prevent the lower sash distorting.
