Tensile Load/Installation Pull Guidelines
• Limit 90º bends in conduit to 2• Cable should not be pulled through a length of
conduit exceeding 30m (100 ft)• Support cables every 4 - 5 ft (1200mm - 1500mm)• Avoid sharp objects, turns and corners• Use a pulley or a third man at turns and corners• Do not “jerk” cable• Pull around obstructions (HVAC) as required

Ducts and Conduit Guidelines
• Fiber and copper pulled in separate conduit− Use innerduct if in same conduit
• Clear internal obstructions, ream conduit ends, and use bushings• Pull all cable at same time, if possible• Use a partner at the entry point• Use lubricants if necessary (do not use petroleum-based)• Pull in a continuous manner without stopping• Do not pull a pull line through at the same time as the cable• Do not pull a terminated cable through the conduit• If pull boxes are used, pull to the first box, coil up the cable, then
feed it back into the pull box and then pull through to the next one
