The SASHSTOP Original was the first model that we designed, it has been created to allow internal and external operation independently from one another. This patented mechanism is what gives the product the versatility and allows it to be used within a number of different scenarios and circumstances.

Our SASHSTOP Original can be used on PVCu and composite doors, but a recent modification has allowed an additional part to be used with the product for use on Wooden doors as well. Installation to these types of doors might differ slightly, however when used with the SASHSTOP Installation Jig it can ensure that the product is correctly and reliably installed each and every time.
