Screw Jacks

The effortless way to open your conservatory windows.

High grade, heavy quality brass.

Precision engineered.

Comes complete with brackets, and screws.

Just fit your winder pole into the looped end of the screw jack and wind it, and your window will open.

If your window is within arms reach you could also consider installing a manual screw jack, that comes with a small integral opening handle.

No need for additional locks, as Screw jacks will also act as a locking mechanism for your conservatory skylights and windows.

They cannot be physically pulled apart.

If you require a conservatory winder pole to operate your Screw Jacks, just click on this link to take you to our Winder Pole page.

We have a comprehensive range of excellent matching winder poles, fixed and telescopic, to make opening your “out of reach” conservatory windows even easier.

"I look after all the conservatory parts, and check them before they leave here, it’s all quality!"
