Do Shin and Echo edgers have the same shaft thickness?

I was wondering if the handles are interchangeable.

Most trimmers of this power range sport a 1" tube. It's a handle and not a precision instrument, it will fit :duhh...

Well, it depends on what model and handle you are trying to swap around. As for the Shindaiwa all should exchange except the T270/272, T3410 etc.

All the edgers and smaller sized trimmer have all the same exterior tube size.
