What is the size of the center post? I'm assuming that since it's a 4" clamp that the post is 4" but I'd like to get an actual size if possible. Thx

The post is 1-3/8" diameter. I have been extremely happy with my stand. Well worth the price.

The center post is about 1-1/2" - The 4" clamp refers to the base that clamps on to the desk - that is 4" wide and 4" deep

Measuring mine I find it to measue a little over 10/16 (inside diameter). The inside post which slips into the center of your bed post is 3/8. They work great!

Some answers state 1, 1 1/2-2 inches while 1 answer states it can actually accommodate 3 inches. Is there anyone who knows exactly the clamp width? I have a 2 inches thick headboard therefore 1 1/2 would not work but if it can really accommodate 3 inches then it would work for me! :-) Thanks!

The "U" shaped brackets were smaller than what I was trying to do... I wanted to mount it on my mountain bike. The "hose clamp" style worked great, and has a pretty long size range. Sorry I don't have an actual measurement.

Each clamp pad is 1 3/8 inches long. The screw center in the clamp is 11/16 of an inch. Butting the 2 pad ends together gives you a total length of 2 3/4 inches long. With pad clamps butted together, center to center of holding screws is 1 3/8 inches. Hope this helps.

I think a 5" post would be pushing the limits of the clamp width. I would step up to the larger size.

I put the calipers on my bike post and it shows it to be one and one-sixteenth inches (1-1/16"); I had to use two of the three plastic shims that come with it to make the rack fit properly on the post. Without taking the rack off to measure the opening without any shims in place, it appears it should accommodate a post upwards of 1-1/4" thick. With all three shims in place it should probably fit a post as small as 1", or possibly just a little less. The three shims included should allow it to fit about any standard post, I would think, but not sure what acceptable standard post sizes really are.

What size is the post that goes into the base. If it is 1/2 inch I would be able to use it with a universal wall bracket that I have. Thank you, Lewis

I tried to measure the "post" diameter, but I could not get to it from underneath and the saddle itself is attached with some sort of #3 Hex Cap that I could not seem to remove (like it is attached with red loctite?) The outer diameter of this hex-cap is 1.258", so the hole under that must be smaller (and apparently "threaded"? I will try to post some photos in a review momentarily.

My center post broke, got a replacement, it broke....http://www.ereplacementparts.com/disc-stem-p-707798.html. I threw the whole thing away. I'll get something different.

It is an adjustable clamp. I don't have time to measure the seat post at present but I believe I answered someone else that the clamp/seat are presently being used on a post that tapers to 7/8".

The clamp that came with my light is a total of 2.4-2.5 inches (measured on the inside not including the metal plate on the top of the clamp used for maintaining position). It can fit up to 2 inches. The table mine is attached to is a little under 2 inches and it fit with some room to spare. It will not fit much more than that since the entire clamp is only about 3 inches long. Hope this information helped.

Hey Gary, Thanks for asking before ordering. It comes with clamps and they are 2" to reflect standard Olympic size. Hope that helps. Let me know if you have any other questions. Regards

It has several innovative points of connection, including the small 3/8" rod adapters you see on the right side of the picture that aren't in the main mouth of the clamp. In the main clamp it seems it would go as small as 1/2". I regularly use it on 3/4 and have used in on 2". It's hard to find a more versatile clamp.

I don't have center mount/arm available to me right now so I can't measure it and be exact for you. I do know it's the middle of the 3 arms. If memory serves me it's 4 or 5 inches long. I have 3 of these all the same length & 1 of the short @ 2.5 inches +/-. Hope this helpsMark

I contacted the company and they said when ordering from them just make a note you want the 2" clamp.Amazon how do we do that here when ordering these?
