We've taken our most popular door-sized cremone bolts, and reduced them to work on your windows. Often used on double windows, cremone bolts allow the user to activate two separate locks at the top and bottom of the window with one handle. Some buyers use a set on one door of a pair and a slide bolt lock on the other, while other buyers prefer to use a cremone bolt on each window. Set includes two bolt rods that can be cut to shorter lengths to accommodate your window. These locks will fit windows up to 6' tall. Available in polished brass, antique brass and oil rubbed bronze. All mounting hardware included.
