The SBH Extra Box is the economical solution between the SBH Light Box and the SBH Standard Box.
The stronger trench shoring plate construction allows higher loads compared to the Light Box. With the same earth pressure the deformation in the trench shoring is reduced considerably.
With the flexible spindle, the SBH Extra Box can be installed where the ground is not stable and using the “cut and lower” method. The use of a reinforced post profile makes the trench shoring box very strong and it meets any specific requirements.
