Before you begin

3 steel adjustable Support props supporting ceiling Before you select the prop you’re going to use you need to consider the height that the prop needs to extend to and the weight it will need to support.

If you are supporting a material such as drywall, the weight of it will be clear at purchase (the average 48″ (122cm) drywall sheet weighs approximately 26kg (57lbs)).

If supporting a wall or ceiling, the weight you are supporting can be estimated by a structural engineer or there are many online calculators which can estimate the weight from aspects such as the floor supports, ceiling beams, roof rafters etc.

Using a support prop

When you know how high you need the prop to extend, you can secure it.

In lightweight adjustable support props this can be done by twisting the tube, or if using a steel prop, insert the pin into one of the holes on the inner tube.

The prop needed will depend on the height and weight of what needs supporting and each type of prop has different specifications.

Adjusting the height
