Product Components

Steel Prop jack

1. Head and base plate for securing to timber beams or facilitating the use of accessories.
2. Inner tube diameter enables standard scaffold tubes and couplers to be used for bracing purposes.
3. The outer tube accommodates the thread section and slot for fine height adjustment. Reduction couplers enable standard scaffold tubes to be connected to the steel prop outer-tube for bracing purposes.
4. The thread on the outer-tube provides fine adjustment within the props given range. The rolled thread retains the wall thickness of the tube and thereby maintains maximum strength.
5. The prop nut is the self-cleaning steel prop nut that has a hole at one end for easy turning when the prop handle is close to the walls. An extra nut can be added to convert the prop to a push-pull strut.
