34 THE BLUE BOX LT MAKING UP CAT. 5 CABLE WITH RJ45 CONNECTORS
LCDBBMUCAT03Sept08
REASONS WHY IT’S HARD TO MAkE
GOOD CRIMPS ON Rj45S (Continued)
expensive, solidly made crimping tools did not make good
crimps. The best and recommended crimper is provided
in the LC&D Crimping Kit. This crimping tool has no “stop”
feature. The no “stop” feature allows “over-crimping”
to ensure the wires are seated correctly; and thus it is
possible to get the center contacts properly engaged.
THE RIGHT MODULAR CONNECTOR
After much research, we found a modular connector that is
easy to setup and makes it possible to crimp a perfect Cat.5
cable every time. The brand is “EZ RJ45” (shown in figure
1.11). It allows for faster terminations and is compatible
with our crimper tool.
The EZ RJ45 crimp has holes in the front of the connector
which allow the 24AWG wire to protrude from the end
prior to crimping. (shown in figure 1.11) This will ensure
proper wire color arrangement and will also ensure that
the wires will be pushed all the way into the end of the
RJ45 connector.

The “EZ RJ45 Crimping Tool” (shown in Figures 1.12a and
1.12b) is specifically designed for these connectors and
will cut through the excess wires protruding from the end
of the RJ45 connector when crimped down.
It has some professional features such as the large crimp-
ing head but it is not capable of “over-crimping” to ensure
that the center conductors have really been engaged.
Though this crimper is very convenient; it will NOT make
good crimps. Use only the ratcheting crimper provided in
the LC&D Crimping Kits. Thus it may ONLY be used as an
initial crimper/cutter and then give the crimp multiple hits
with our recommended ratcheting crimper.
One can use the “EZ-RJ45” connectors with any crimper. It
just requires that the excess wire is cut off very close to the
end of the connector; this can be done with flush cutters.
Care must be taken to
prevent any excess wire
protruding from the end
of the connector since
this will prevent the
connector from seating
properly in the jack.
There are two wiring
standards used for mak-
ing Cat.5 cables; 568A and 568B. Either one may be used,
as long as it is consistent along the bus. This manual refer-
ences the 568B convention in the examples and images.
This crimper is available in the LC&D
crimper kit. It is also private labeled
under many brand names.
