mm) when pushing the connector tube into the
cable core tube. To tighten, hold the connector in
place while turning the nut. then remove the rod
from the core. This procedure ensures the inner
core does not kink while assembling or tightening.

tapered end is 4.68 (119 mm) from the incoming
connector (see Figure 5). Lock into place with steel
housing. Plastic strain relief may overhang cable
jacket a maximum of .43" (11 mm).
