1.0 General Infor mat ion
The purpose of this best practices document is to provide a set of step by step instructions describing the installation
of wire mesh pulling grips on non-armored and single armored cable. The methods and procedures contained
herein are designed as a guide. Since there are numerous methods which may be utilized, these methods
described herein have been determined are the most effective and efficient. The recommended procedures are
based on average conditions.
In addition, the materials and hardware referenced herein appear as the recommended items, but in no way reflect
the only tools and materials available to perform these evaluations.

3.0 Installation Procedure for Dielectric and Armored Outside Plant Stranded and
Indoor/Outdoor Central Loose Tube Cable
3.1 Select the proper si ze grip for the cable on which t he grips are to be installed. Me asure the
outside diameter (OD) of the cable and select the appropriate grip size for that diameter as
specified by the pulling grip manufacturer.
3.2 Strip approximat ely 3 feet o f c able to ex pose the cable core and outer st rengt h members (OSM)
where used. NOTE: For 2 to 12 fiber indoor/outdoor central loose tube cable, remove only 1 foot
of outer sheath, lea ving the ripcords intact, an d proceed to step 3.5b loose tube cable only. Reference appropriate Panduit Sheath Removal Procedure Best
Practices for detailed ins tructions . Be especia lly caref ul not to cut all the way through th e jack et
and damage the OSM yarns.
3.3 If the cable is armored, remove an additional 7 to 10 inches of the ou ter jacket down to the
armor by shaving the out er jacket away from the s teel armor with a sheath k nife. NOTE: T he
use of a heat gun to s of ten the s ec t ion of o uter jac ket to be removed may facilitate this proc es s.
Do not overheat the cable. Do not damage the armor.
3.4 Starting at the end of the jacket (or armor, when cab le is armored), wrap one layer of friction
tape around the cab le OSM (when present) and core for a distance of approxim ately 5 inches.
Cut the tape and secure the end tightly.
3.5a Outside plant stranded loose tube cable only: Slide the pulling grip over the exposed core and
OSM (where present) so that approximately 1/3 (7 to 10 inches) of the m esh grips the jacket end
and 2/3 grips the exposed core. If the cable is armored, slide the grip back over the exposed armor
so that the grip butts against, but not over, the outer jacket. Tighten the grip over the cable by
grasping the eye of the grip and smoothing the mesh to draw it tight. Proceed to step 3.6.
3.5b Indoor/outdoor central loose tube cable only: Slide the pulling grip over the exposed core so
that about 3/4 of the mesh grips the jack et end and 1/4 grips the exposed core. Tighten the grip
over the cable by grasping the eye of the grip and smoothing the mesh to draw it tight.
3.6 Starting with the cable jack et at least 1 inch be yond the wire mes h, tightly wrap over the assem bly
with vinyl tape to the other end of the mesh.

4.0 Installation Procedure for Dielectric and Armored Outside Plant Ribbon Central
Loose Tube and Outside Plant Bundled Central Loose Tube Cable
4.1 Select the proper size grip for the cable on which the grips are to be installed. Measure the outside
diameter (OD) of the cable and select the appropriate grip size for that diameter as specified by the
pulling grip manufacturer.
4.2 Since outsid e plant r ibbon central loose tub e an d outside plant b undle d centra l lo ose tub e cable
do not have yarn strength members or a central strength member, there is no need to prepare the
end of the cable. Simply cleaning the cable jacket to ensure the absence of slippery waxes or gels
is the only preparation necessary.
4.3 Once the jacket is cleaned and the outs ide diam eter is check ed, place the entir e length (24 inches
minimum) of the proper size mesh grip over the jacket. Placing this length of grip over the j acket
will completely couple the pulling load (600 lbs. max.) to the two strength member rods located
beneath the jacket.
5.0 Installation Procedure for Dielectric and Armored Outside Plant Ribbon Stranded
Loose Tube Cable
5.1 Because outside plant ribbon stranded loos e tube cable has a r elatively large diam eter, a grip
sized to fit over the cable ja ck et will not lik el y fit into the s ubduct. T hus, the f ollow ing proce dure
has been developed for fitting the grip over the central strength member (CSM).
5.2 Strip approximately 2 to 3 feet of cable jacket from the end of the cable to expose the cable core
(dependent upon lengt h of grip being used). Use care when ring cutting the s heath to avoid
damaging or cutting the out side str ength m em ber yarns (OSM) . Remove the j acket and unwin d
the OSM yarns.
5.3 Unwrap and discard any water swellable tapes. Cut the buffer tube binders, unwrap, and
remove back to be ginning of the sheath. Cut the buf fer tubes approximately 1 inc h from the
beginning of the sheath and discard them.
5.4 Remove any water swella ble tapes or yarns from the CSM. Star ting at the end of the sheath,
evenly spiral wrap the OS M yarns around the CSM. Again starting at the en d of the sheath,
evenly spiral wrap 1 layer of friction tape over the CSM/OSM to the end of the CSM. Ideally, the
tape should form a smooth wrap and cone up to the jack et sheath to reduce the chance of the
cable end snagging during installation.
5.5 Choose the appropriate si zed grip. For 432 and 864 fiber count, use a 0. 33-inch to 0.50-inch
sized grip. For 1152 f iber count, use a 0.64-inch to 0.87-inch s ized grip. There may be slight
variation in sizes among grip manufacturers.
5.6 Slide the grip over the friction tape and down to the end of the jacket.
