The baypole jack from Window Widgets stops windows moving and bricks cracking, so installers know their windows will be safe and structurally secure for the long term, according to Window Widgets.

Window Widgets’ jack is CE marked and BBA accredited. It is certified by itself, and tested and certified to be used with the Window Widgets baypole.

Managing director Martin Dickie said: “There wasn’t a BBA accreditation for jacks, so we worked with the BBA to create one. Our baypole and jack have been tested separately and together. Testing them together means we know they join correctly and can hold the weight they need to without breaking.

“Using our jack means installers know they’re getting a high-quality product that works, and has all the right certification. And its CE Marked so it’s legal.”
