With every screw jack window opener you'll need a set of brackets to attach the opener to your window and window sill. One option for screw jack openers is the Large 3 Hole Mounting Bracket. And at Rocburn we can provide you with spare brackets in case of damage to your existing set, as well as a set with your screw jack when you order from us.
With the 3 Hole Bracket you simply have to attach to the window frame or ledge. It's a tough, cost-effective option that works well with conservatory windows and vents and allows for easy opening and closing through the screw jack.
