Bending ConQuest ®
Bending ConQuest ® (Underground)
ConQuest can be easily shaped by rolling a bend into it. Take 10 – 12 feet (3 – 3.5 meters) of conduit and pull the
free end of it toward you forming a “horizontal U.” Push into the bend lightly and roll the entire radius of the conduit
forward. DO NOT bend the conduit any further if it begins to show signs of ovality, i.e. begins to bulge. DO NOT
press down on the conduit with your foot as you bend it.
Bending Radius (ALL)
Conduit is often routed around corners during placement and pulling tension must be increased to apply adequate
force to conduit to bend the conduit around the corner.
CommScope’s specified minimum bend radius is the static (unloaded) bending radius of the
conduit. This is the minimum radius to which the conduit can be bent without mechanically
degrading the performance of the conduit.
The bending radius of conduit and cables during the construction process are controlled by
construction techniques and equipment. Use the largest bend radius possible to help reduce
overall pulling tension.
WARNING: Exceeding minimum bending radius can result in permanently ovalizing the conduit
which may restrict cable installations. Exceeding minimum bending radius of cables can damage
the electrical or optical performance.
