BURN THROUGH (CABLE PULL)

Fiberglass conduit is an excellent material for avoiding “burn through” when pulling cable.		NoYesYesNoNoNo

COEFFICIENT OF FRICTION

Using PVC Jacketed Cable
Fiberglass conduit offers one of the lowest coefficient of friction available today for conduit systems. It is completely resistant to any of the current pulling lubricants corrosive properties.		0.38 0.90 0.90 0.550.550.25
