I am so pleased I invested in the Sashmate; it has given me an extra arm meaning I can do a job by myself when I need to remove a window from the frame, whereas before I would not have attempted it on my own. The Sashmate makes my job when dealing with friction stays, hinges and window locks etc. so much quicker and so much easier, not to mention safer. I would highly recommend the Sashmate; it is my new employee that I don’t have to pay.
