- How do I know I’m choosing the right screwjack window opener?
We try to include as much detail as possible on all our product pages including things like – item descriptions, technical details, specifications, measurements, applications etc to help our customers ascertain if it is the right product for them. If you are unsure whether a particular screwjack is the right one for your window, then please then do not hesitate to contact us and a member of our team will be happy to help to make sure that you get the correct product for your window requirements.
- Can I use screwjacks on a vertical window?
Yes, but only if the window is at a low level. If your window is out of reach, a screwjack is not suitable. This is because the winder pole must be held in alignment with the screwjack’s thread when turning. If your window is high level this could be well above your head. See this illustration for more information.
- Do I need to grease my screwjacks?
Generally speaking no, but it also won’t do any harm if you do. Should you wish to lubricate yours, then we suggest a dry lubricant as this will look better and help to stop dust build up.
