Multi-Bay configured Slide Rail System utilizes unique parallel beams that roll up and down the slotted rail on the inside face of Slide Rail linear posts. The parallel beams have spreader collars—like trench shield sidewalls—which pin standard trench box spreaders.
LINEAR Multi-Bay System which has open ends on the trench and does not use corner posts. This configuration is ideal for installing long pipelines, even over great distances. The open ends allow contractors to install pipe in the front bay, while back-filling in the back bay and then “leap-frogging” the system forward. In this manner, it is possible to re-utilize a set number of Slide Rail components. Additionally, with both 4-Sided and Linear Multi-Bay, when external waler beams and sacrificial members are utilized, the parallel beam spreader assembly can be completely removed, providing an unobstructed clearance for installing longer pipe or structures.
