Concealed Restrictor Catch for UPVC Windows

 Window restrictor arm for upvc double glazing windows, often known as a concealed restrictor as it sits in between the frame and sash and so cannot be seen when the window is closed.

Great for rooms where there is a higher risk of accidentally falling out.

Supplied as 1 restrictor with 1 stud,  extra studs available for 95 pence each
