Note, you should always follow manufacturer’s
instructions or procedures. Fig. 1
When you first come to fit your Cable Grip, you will
probably find that the conductor has been cut using
some shearing Mechanism, for example a parrot beak
cutter. This method of cutting leaves a very sharp edge
on the end of the conductor, as Figure 1 shows.
In order to obtain maximum strength from your cable
grip, it is extremely important to remove the sharp edge
and it is very easy to do, only taking a minute or two.
Figure 2.

A rule of thumb for the amount of chamfer on the Fig. 2
conductor, is approximately 30° chamfer for a distance
of approximately half the diameter of the conductor.
This applies whether the cable is a solid copper rod, or
a stranded aluminium conductor.
When you unpack your cable grip, you will notice that
the end has probably closed over, similar to that in the
photograph illustration. Figure 3.
This does not mean that the grip is in any way
damaged. You will need to open up the mouth of the
cable grip before trying to fit it on to the end of the
conductor. To open up the cable grip, all you have to do Fig. 3
is, by hand, manipulate the wires at the end until you
get a nice opening as per the photograph. Figure 4.
If you are going to fit the cable grip to a stranded
conductor or even a wire rope, it may be necessary to
use some PVC electrical tape. Tape down the end of the
conductor for about 25mm. just to prevent the strands
from coming out of their formation and snagging or

catching on the inside of the cable grip as it is being
fitted. It is now just a matter of putting the mouth end
of the cable grip against the end of the conductor and
slowly working it on.

In the picture, Figure 5, the conductor has been
pushed into the cable grip as far as it can go - right up
to the very shoulder of the cable grip. Once you are
sure it is in as far as it can go, ensure that all the slack
or the loose spots along the grip have been eased out
towards the mouth end.
