With this method we use vacuum extraction to install a a draw string in pipes, conduits or ducts, we perform this work for various industries including electrical contractors.
This is the preferred way of installing a draw rope for many contractors and at times its the only option. This task is performed by setting the vacuum hose on one end of the underground conduit, on the other end we insert a light string with a small plastic nose, in the past we have been able to suck the light draw string 150 meters.
