Prepare the conduit and pull rope.

•  Verify that major construction is complete.
•  Verify conduit and pull rope has been installed 

properly. Reference TraceTek document 

H58175 for general information.

Note that conduit dimensions and related parts can vary 

between projects.

•  Verify that the pull rope is free of knots and splices 

and that there is 6 feet of extra rope at both ends of 

each section.

•  Two people are needed to manage the pull rope. One 

person is on each end of the end pull rope, and each 

person must be able to communicate with the other in 

case of problems during the pull.

•  The person feeding the pull rope into conduit needs to 

maintain slack at all times.

•  Pull the sizing tool from one end of the conduit  

section to the other. 

•  Verify that the sizing tool pulls freely through 

each section of conduit. Pull with a slow steady 

motion. Do not use excessive force on the pull 

rope, as this could damage the conduit.

•  As you pull, coil the pull rope by hand and keep the 

pull rope out of the dirt by placing it on cardboard or 

plastic sheeting.

•  If the pull rope becomes stuck, do not increase 

pull force-instead pull the rope in opposite 

direction for a short distance, then try repulling 

in original direction with normal force.

•  Shake the rag attached to the sizing tool free of excess 

debris. Remove the rope section containing the rag 

from the sizing tool. Replace the rag with a clean rag if 

necessary, and then attach the rope section with the rag to 

the eye splice in advance of the sizing tool.

•  Reverse the pulling direction to bring the sizing tool 

through the conduit in the opposite direction, and return the 

original pull rope back into the conduit. Remove the sizing 

tool and rope section with rag from the pull rope.

•  Verify conduit ends are marked for example, with different 

color conduit endcaps or tape to indicate direction 

(towards or away) relative to TraceTek alarm module.

•  Arrange excess pull rope by coiling around the riser pipe 

and taping in place.

•  Cover conduit ends to maintain cleanliness within conduit. 

Use a plastic bag taped in place, or stuff a clean rag into 

conduit end.

Conduit Cleaning:

•  Even if the conduit was proofed with a conduit cleaning 

tool during the conduit installation process, it is 

recommended to clean and check clearance of the 

conduit immediately before installing cable in order to 

avoid damaging the cable.

•  Attach a rope section with a rag tied to the eye splice in 

advance of the sizing tool.
