The Paratech LongShore Struts are comprised of a 3” diameter threaded aluminum movable shaft that extends out of a 3½” diameter aluminum tube. The square thread allows full surface contact of the shaft through the collar and the collar full surface contact on the tube to transfer the load directly to the ground. LongShore Struts can be extended manually or pneumatically with air, carbon dioxide or nitrogen. LongShore rescue struts are the perfect choice for exceptionally heavy loads or longer length shores.
