Vertical Aluminum Hydraulic Shoring are typically used in linear trench applications and are installed from outside the excavation. The shores are hinged so that they can be folded when lowered into the trench and then opened up and pressurized with a hydraulic hand pump.
These shores are 10' long in the vertical direction and include heavy duty plywood. Choose the cylinder size you need according to the width of your trench as directed by a competent person certified in trench shoring. Each rail used three cylinders.
