Telescopic screw jack openers are made with a twin thread to provide extra strength and durability. It means they can be used for opening heavier windows and vents and they won't need to be replaced for a long time. Here at Rocburn we offer chrome and brass twin thread telescopic openers, including the ST706-350-SB for use with small brackets.
The window opener provides a maximum distance of travel of 310mm and locks in place once you've set the distance you want. You'll need a winding pole to open and close the screw jack if positioned on an out of reach window and we can supply these too - just be sure to ask when you place your order with us.
