Paratech manufactures high-strength, low weight, aluminum waler equipment. Paratech’s modular waler rails come in 18 in (45,7 cm), 6 ft (1,8 m), 8 ft (2,4 m) sections, and can be connected together through the heavy-duty waler connector. With the waler stop block, rescuers can solidly lock strut bases into the waler rail before lowering it into the trench. With the L-trench adapter set, inside mechanical thrust block, and outside mechanical thrust block, rescuers can shore corners and angled trenches. Paratech also offers a waler system kit with all the necessary components to shore a straight trench.
