Q: 1. What is the OVERALL length end-to-end?...and, what is the size of the OPEN jaw, i.e.., what size object can the open jaw accommodate?

A: The actual post is about 8 (inches) long. The bottom half of the clamp to the top of the post is 5 long. Within the clamp jaws you could fit a 3 1/4 item. I wouldn't go larger than 3 though. I use it to hold boom poles on C clamps. Works great!

Q: 2. Has anyone used these with the Scrim Jim Cine frame for attaching to a C-Stand or something similar (which is the new iteration of scrim jim)? Any thoughts? Thank you!

A: I use them for this purpose and they work great.

Q: 5. Is the hole on the top: a 1/4-20" OR is it 3/8-16" on the inside? I mean can I use a "Matthews Baby Pin 5/8" with a 3/8" Threaded Tip", into the hole - on the top of this Mini Clamp? Or do I need a "Baby Pin with a 1/4" Tip"?

A: We have two versions, one with a 1/4"-20 female threading at the end of the pin, which is what i believe you are asking about. We also have a Mini Matthellini with a male 3/8"-16 threading at the end of the pin.

Q: 6. How do I remove the pin on the jaw clamp in order to add this extender?

A: The 5/8 pin on the Matthellini End Jaw clamp is not removable. The Extendellini is designed to widen the jaws of the Center Jaw Matthellini PN:420100. The turn knob and bottom jaw are removed from the shaft, Extendellini is fixed onto the end of the shaft and the turn knob and jaw are mounted onto it.

Q: 7. How do I remove the pin in the clamp so I can remove it and add the extender?

A: I’m not sure what pin you are talking about, but the extenders I am familiar with just clamp onto the end. You may have one of the Matthellini clamps that are configured different. There are about 3 or 4 different Mattellini clamp versions. I have found that sometimes you have to use a short one with an extension to make it work for what I want to do. I have 3 or 4 clamps in different sizes and they are each made different, so many times I try different combinations until I find what works best. They work great and are very solid unlike some clamps that have their use but move regardless of how much you tighten them

Q: 8. Is it compatible woth Kupo cstand arm and arm grip?

A: You can use it with a grip arm.

Q: 9. Can two of these Matthews Matthellini Clamps be attached together for a parallel double clamp?

A: Not at this time.

Q: 10. I have a Matthellini clamp that looks just like this and want to buy a second one. However, the jaw I have is 3 wide. Is this 3 wide or only 2 ? I can't find a 3 version at B&H. Thanks.

A: This clamp is 3 wide. The 2 , I believe, refers to the depth of the clamp - from front to back of the jaw.
