Propalock is the new, innovative locking system fitted to adjustable telescopic steel props.

Propalock is the new, innovative locking system fitted to adjustable telescopic steel props. Manufactured in accordance with British Standard (BS 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 fine 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.

A 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 posifion 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.







In the construction industry, compliance with key regulations and standards is essential for ensuring safety and structural integrity. The Construction Design and Management Regulations (2007, updated in 2015) establish fundamental safety principles. British Standard 5975:2008 guides temporary works practices. Health and Safety Executive publications like RR 463 and RR 204 provide insights into preventing structural issues during refurbishments. These resources collectively promote safety and compliance, fostering secure construction environments.
