The Acorn sash stop fits into the side rail of the upper sash & is cut in flush, the Acorn on its chain is attached to the top of the lower sash & is retained there when not in use. When the Acorn is screwed into its plate it will act as a stop, therefore allowing the sashes to be secured open in the ventilated position.
The sash screw passes through the centre rail where the sashes meet; therefore locking them, as no vertical movement can then be achieved. Acorn Sash Stop & Chain 32mm
