Vertical Hydraulic Shores or “trench jacks” (as they are sometimes refereed to) are a combination of hydraulic cylinders connected to rails that are ideal for use in primarily stable soil conditions. Some of the major benefits of vertical shores are that they are quick, safe and simple to use. They are also designed to be installed and removed from the top of the trench 100% of the time. They can be used for spot bracing for repair situations, or can be used for production trenching.
