Each unit comprises 2 No. aluminium or steel rails complete with two hydraulic cylinders. The cylinders fit directly on to the rails and are pressurised by a manually operated hydraulic hand pump, giving an uninterrupted column of strength between the trench walls. All units are designed for quick and easy assembly, installation and extraction by one or two people from outside the trench. All units are fitted with mechanical lock-off valves for additional security and to further simplify the installation and extraction process.
