result of termination shall be no greater than 0.5 inches (13
mm).
4. Shall be installed according to manufacturer’s instructions.

16. Do not install Category 6 or 6A cable with more than 110N (25
lbs) pull force, as specified in ANSI/TIA and BICSI TDDM

to reduce pulling friction to acceptable levels on: long pulls
inside conduit, pulls of multiple cables into a single small bore
conduit, on conduit runs greater than 100 lineal feet with bends
of opposing directions, and in conduit runs that exceed 180
degrees of accumulated bends. Use of tensile rated cords (i.e.
fishing line) should be used for difficult or questionable pulls - to
judge to go/no-go condition of the conduit and pulling setup.
17. Care must be taken so that the cable does not bend at any
location to a radius less than ten times the diameter of the
cable. A cable feeder guide or rollers of suitable dimensions

should be used between the cable reel and the face of the duct
to protect the cable and guide it into the duct as it is pulled off
the reel.
18. As the cable is pulled off the reel, it should be carefully watched
and inspected for sheath defects. If defects are noticed, the
pulling operation should be stopped immediately and the
Engineer promptly notified of the defect. Kinks and/or other
irregularities in the cable sheath should be removed or
corrected as directed by the engineer.

preserving wire pair twists as close as possible to the point of
mechanical termination. The amount of untwisted in a pair as a
result of termination to the jack shall be no greater than 0.5
inches (13mm).
4. Jacks shall be installed according to manufacturer’s instructions
and properly mounted in plates, frames, housings or other
appropriate mounting device.
5. Jacks shall be installed such that cables terminated to the jacks
maintain minimum bend radius of at least 4 times the cable
diameter into the IDC contacts. Cables shall be terminated on
jacks such that there is no tension on the conductors in the
termination contacts.
