What are screwjacks?

Screwjacks, also known as traditional window openers comprise of a threaded rod that is rotated using a winder pole or handle, opening the window or roof vent. Screwjacks are suitable for a variety of applications but are particularly popular for conservatories, orangeries and skylight windows on pitched roofs as well as flat roof vents and low-level windows on vertical walls.

At Rocburn we stock a comprehensive range of screwjack window openers in a selection of lengths and bracket options to make opening your window as simple as possible. Whether you are looking to install new openers, require a replacement opener or screwjack window winders, we have everything you need right here.

Types and Components

Screwjacks come in a variety of options with different threads, colours, handles, and finishes.

Below are examples of each option.

Handle and Pole Screwjack

Operation by Handle or Pole

The height of your window will help to detirmine which screwjck you need. If your window is within reach, you could consider installing a screwjack that comes with a small built on opening handle. Alternatively, just hook in a winder pole on the screw jack and rotate to open the window.

Screwjack Comparison Single and Twin Thread

Twin Thread or Single thread

Twin thread or ‘telescopic’ screwjacks have a 2nd screw thread concealed inside the first and have a longer stroke compared to a single threaded option.

As the additional thread is hidden when the window is closed these screwjacks are less prominent on the window frame.

Frequently Asked Questions

How do I know I’m choosing the right screwjack window opener?2023-07-13T14:09:00+01:00

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.

Can I use screwjacks on a vertical window?2023-06-02T14:04:12+01:00

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?2023-06-02T14:03:51+01:00

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.
