A square nut is used within a square spent travel conduit to restrict the distance that the helical cable driving the gears of your window opener can travel. The T720 square nut is made from brass and is best used with the T410 or T411 square conduit. At Rocburn we can offer you them both together along with chain openers and operators for your windows.
Talk to one of our team when you place an order for a window opener or operator and we can make sure you also order all the smaller bits and pieces like square nuts, spring stops and helical cable that you'll need to keep the opener in perfect working order.
