Related Questions and Answers

Q: 1. how much weight can this support? thanks

A: This item does not have a specified limit.

Q: 2. 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.

Q: 3. Do these fit the Matthews brand Matthellini clamps perfectly?

A: You can easily make this fit by trimming it, this employs peel-and-stick application.

Q: 4. The Cardellini website lists the shaft length of this item as 11", not 13" as stated here. Which is correct?

A: The total length of the Cardlini is 11"the rod length is 9"

Q: 5. 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!

A: Not at this time.

Q: 7. What is the overall length of this from end to end?

A: From the top of the clamp to the end of the post, it's approximately 7.125 .

Q: 8. How about the spec of thread of those screw holes on the end of rail? I would like to mount RRS PCLR clamp on end as a vertical nodal slide of my DIY multi-row pano nodal slide gear.

A: Screw holes are 1/4-20".

Q: 9. What is the depth of this rail?

A: The depth of this rail is approximately 1/2"

Q: 10. Hi, help me understand whether that rail could be used for macro / close-up shots. I understood it's only adjustment of camera's position height relatively to object photographed (instead of extending the tripod's central column). Right?

A: It could technically be used for macro photography, the difference between this and an actual macro head is that a macro head has a knob that can mm by mm move the camera forward or backward to make precise adjustments. If you use this, it has the markings of where you need to move it to, but it doesn't have the knob to make the micro adjustments.
