This perimeter support system provides for an unobstructed shaft, and is generally used to secure pits for pump stations, the installation or rehabilitation of manholes, tanks and vaults, or the operation of trenchless technology equipment. Features include: • Modular construction • Four-way hydraulic support with high-yield telescoping steel sections • Four-way hose bridles for simultaneous cylinder pressurization • Provides active support to secure safe excavations in less stable soils
