It’s important to select the correct product for a sash security restoration project and whether it needs to be lockable or suitable for fire egress. Follow our instructions on installing security onto sash windows.
Firstly, check whether the lower sash has horns protruding up from the meeting rail. If so, make sure there is enough room on the horn for the stop to engage onto.
Mark the top sash just above the meeting rail, on each side. This is where the stop will sit when fixed into the sash.
Refer to the individual fitting instructions of the sash stop for specific methods on hole sizes etc.
Once the sash stop is fixed on both sides, test the operation by opening the fastener and trying to lift the lower sash upwards.
