As I understand it, the handle on the clicker type wrenches has a pivot
point built in to it so that you apply force at a specific point on the
wrench to get "true" torque.
I'm going strictly off what I have read in manuals for the clicker type
wrenches, and as someone else has pointed out the manuals for the
clicker type state NOT to use any type of extension.
Plus, a handle extension wouldn't help anyway. You can't apply torque
beyond what's set on the clicker type, since it "clicks" once the set
torque is reached. For example, if you set it for 100lb-ft it will
"click" once that torque is reached, there's no way to accurately go to
120lb-ft with an extension if the wrench is set to 100lb-ft.
