STEP 1:
Transverse Connector __________________________________
Transverse connectors may be placed to
connect rod segments together. They
may be placed between adjacent rods to enhance torsional stability of the overall
construct. Three different lengths are
available. The middle screw should be loosened to allow for length adjustment.
The outer two screws should be loos-­‐
ened to the point that the end of the con-­‐
nector snaps over the rod. Tighten the
outer 2 screws with a torque limi@ng
wrench and then @ghten the middle screw. Turn the wrench clockwise un@l a click is heard.
