Propalock is the new, innovative locking system fitted to adjustable telescopic steel props. Manufactured in accordance with British Standard (B8 4074: 1982 and current BS EN 1065: 1999) its purpose is to contribute to the security and management of safe working practices in temporary works/support situations during construction work.
Propalock is a management tool for the control of temporary support. improving health and safety practices. The universal popularity of adjustable steel props is due to the fact that they provide the simplest, quickest, most reliable and economic method of temporary support at any height between their closed and extended positions. Adjustable telescopic steel props comprise of a large diameter screw thread on the outside of the outer (lower) tube, a collar nut to achieve tine adjustment along the thread, and a loose pin through a series of holes in the inner (upper) tube to give a wider range of adjustment.
Propalock is initially installed to the outer lower tube of the prop. Following normal erection procedure by site staff, Propalock is fitted into its operating position by a responsible person – a temporary works co-ordinator (TWC). It is at this point the TWC assumes control of the temporary works implemented on site.

It’s aim is to prevent unauthorised use of steel props, which can lead to accidents in the work place (i.e. Lockout/Tagout procedure).
