I saw someone compare this one with Gitzo leveling base and I thought this might fit Gitzo 3 series. But when I called RRS, they told me that it won't fit.

I have a Gitzo leveling base, and it's a very tight fit on a G1325.
I use this column with one of my aluminum 3 series Gitzos: https://www.siruiusa.com/index/photo...ml?cid=5&id=35
It fits perfectly.
The corresponding leveling base is: https://www.siruiusa.com/index/photo...ml?cid=6&id=37
I'd contact to confirm that it fits. I'm very happy with Sirui quality.
I do not hike around with any camera due to age and joints, but . . .
I routinely use my 8x10 Kodak 2D without a hesd on a set of Burlbach legs that has a leveling center post . The movement provided by the leveling post is usually enough for the images I make.
I use the old Kodak 2D in Magnesium , rare but very light and solid. Then I use a Gitzo carbon fiber tripod with a small head. Cannot remember model numbers. I do like the Rodenstock 240mm Symmar and although it not the lightest I do like the colour rendering. I can put this all in a carryon bag with two fidelity holders adn off I go I make the weight limits for carry on too.
RRS came out with a replacement for their universal leveling base, lowering the height, and label it as a 2 series: TA-2U-LB. Although I've used my older universal leveling base with SLR's I like the ergonomics of the locking mechanism more than the 3 series (or similar Gitzo) leveling base. The older 2 series leveling base seemed to have the same bowl as the 3 series, but a smaller diameter attachment to the tripod. The load capacity was also the same 25 lbs. I think the universal RRS would handle a light weight 810 camera unless it had a very long extension. Kirk makes a similar universal leveling base: https://www.adorama.com/kirtlb1.html
The RRS 4 series leveling base is much bigger ( 100mm vs 72mm platform ). The load rating is higher at 50 lbs.
Linhof makes a leveling base which is occasionally sold on the used market which "looks sturdier" but actually has a 10kg rating https://www.bhphotovideo.com/c/produ...ead.html/specs .
In spite of the small surface to attach the RRS to a 3 series Gitzo, I would probably buy it if I needed a replacement. https://www.reallyrightstuff.com/ta-2u-lb_2
I have and use this very same head, except it is the previous model with bare metal showing through on the raised pattern on the top and bottom of the head. I can attest that it can carry an 8x10 Chamonix or a vintage 8x10 Sinar Norma with a 508mm lens on the camera. I once had to mount my 11x14 on top of this head (only head I had with me at the time). It was windy, and I couldn't get the image on the GG to be still. Its present new list price makes me sit back in my chair and smile... got mine off ebay for well under $100 and have passed up on others similarly priced. What I did notice in closely looking at the image of the new one and holding mine next to the screen, is that the new one pictured has a 3/8-16 screw and not the 1/4-20 size as mentioned in the text. Visually confirmed without a doubt, trust me. I would love to have a solid 3/8-16 screw to attach my camera to. Having to insert an Oben 3/8"-16 to 1/4"-20 Reducer Bushing ($2.49 in the "Recommended Accessories") into the bottom of my cameras always makes me cringe just a little.
Thanks for the info Bob. Unfortunately the 1/4-20 screw on the top of my Linhof head has only 3 threads. I actually have one of those brass 5 thread bushings that I can screw into the bottom of my camera, but I prefer to use a harder SS metal one (I'm sure better than the $2.49 Oben) since I am ultimately having to depend on only those 3 threads on the top of my Linhof head.
Here's my lightweight Alpinist with a set of lenses ranging from 165mm to 450mm. ThinkTank camera bag, Gitzo/RRS tripod. A joy to use!
