Comments about Matthews Matthews Extendellini for Matthellini Center Jaw Clamp:
When I need to attach a light to a post, beam or some other object that is wider than than normal (Matthellini or Cardellini center jaw clamps) clamping range, I just put on the Extenellini and I'm good to go up to 1 foot wide. I love it, it gives me so many more options.
