Connectorization
QR coring/stripping tools are designed for craft-friendliness and speed of operation. All QR connectors and tools
are manufactured to meet CommScope specifications, therefore any QR tool can be used to prepare the
proper-sized QR cable for any manufacturer’s connector.
Use the right tools: a QR coring tool, a file, center conductor cleaning tool, wrenches sized for the
connectors (adjustable wrenches are fine) and cable cutters. A hi-torque, low-speed drill or a ratchet are optional,
but will speed the process. Wearing safety glasses and gloves are recommended.
Prepare the cable by using the cable cutters to trim the cable to a smooth, round end.
Remove the proper amount of shield and dielectric with the QR coring tool. Slide the cable into the
tool until it stops. With slight forward pressure, twist the coring tool (either by hand or mechanically with the
ratchet or drill) so that the blade begins to strip and core the cable. Continue to turn the coring tool until it spins
freely - the tool has a preset stop that requires no adjustment. Clean the dielectric and shield residue from the
tool.
Clean the center conductor by using a non-metallic cleaning tool. Score the coating on the center
conductor at the shield and scrape it toward the end of the conductor. The conductor is clean if the copper is
bright and shiny. DO NOT USE A KNIFE or other metal tool as it may damage the copper cladding.
Remove the correct amount of jacket with the QR jacket removing tool. Slide the cable into the tool until
the cable stops. Turn the tool clockwise to strip the jacket. Continue turning until it spins freely - the tool has a
preset stop that requires no adjustment. Remove any Migra-Heal ® compound that may be on the
shield.
Slide the shrink tubing (highly recommended) over the cable end, then attach the
connector according to the manufacturer’s instructions. Place and shrink the boot. Note: if you are using a
heat-shrink boot, apply the flame carefully. Overuse of the torch may melt the jacket and dielectric.
