Screw jack openers are traditional style window openers operated manually. They look elegant when in place and can easily be screwed in place onto your window and window sill. And once in place the screw jack will hold your window in place securely so it can't be forced open any further. There's an easy-to-turn handle attached to the thread making adjustment simple.
At Rocburn we offer single thread screw jack openers including a 150mm thread option in chrome. Brackets can be provided for securing the opener to your window, and the opener provides 105mm of max travel opening and 210mm of distance on the handle at its longest.
