Will these work for a curved umbrella base to hold down?

I think it could be possible but not really sure. I don't know if you could put more than one weight bag on it around pole. It does have a long Velcro strap maybe you can somehow lay them on top or something. Good luck

They come as 4 double cylindrical bags in the package which I use to wrap around a tent plow when stakes cannot be used in the ground. If I am picturing a table with a center hole where a large umbrella goes, it may work. If not, I am not sure what you want to stabilize.

Doubtful. It has a larger, 4-prong base/stand that needs to be weighted down. There are specific offset umbrella bases you can purchases to weigh down the base. I use paving stones. Without being weighed down the umbrella will tip over. A standard, castiron base will likely not have a wide enough base to keep it from tipping over (if it would even fit)

Yes. You may need to purchase a hole-saw for the size of your umbrella pole. They often come as a set of bits that work with a standard drill - but they're not expensive. First - make sure that there are no brackets in the path of the hole. You can make the hole a little off center if necessary.

Hello Mamamia, I would say it probably could prevent the umbrella rotating in a light breeze, if you tighten the set screw really hard, but I wouldn't count on it stopping rotation in any sort of stiff breeze, as that umbrella will have lots of leverage to bring to bear on that small area. You may actually want the umbrella to turn in the wind, rather than fall over. The center tube is 1-3/4" diameter on the outside, and comes with inserts to fit two smaller size umbrella poles. By the way, the tube is water-tight, and fills with rain water. It's not a big deal, but it's annoying when you put the umbrella pole in and water gushes out of the tube. Even though it's powder-coated steel, I'd recommend drilling a small hole as close to the bottom of the tube as you can, to let it drain. Otherwise, it's a fine stand!

Have not tried it for an offset umbrella, but based upon the circumference and the weight when filled with sand, I don't think there is enough support to hold your umbrella securely

Yes, I am just using our old base that we previously had & it works just fine. But our base is able to be tightened to squeeze snug to the umbrella.

I'm not sure. I have a Clic Gear umbrella holder. You might check the diameter of the holder.

I guess I don't know exactly what the umbrella base looks like, and I imagine that strong winds combined with the aerodynamic shape of the umbrella could pull along a hefty weight. I've used these for just one crafts show so far and haven't seen them for a big storm yet.

I think it would depend on the nature of the clamp and the size/weight of the umbrella. The arm rests are almost 2 1/2 inches across the top, so I'd think you could get a clamp on those pretty securely. If you're trying to clamp to the side of the arm rests (or the back rest, for that matter), you're only going to have an inch to work with, so I'm thinking that might not be as practical.

For the purpose I used them for they were excelent. They held a nice bit of weight and they were adjustable. I still like them today. If the floor is sloped, there is a little play in them. However, they are not of real high quality. the plastic on the bottom was held with a screw. If the floor does not have a major slope; they will probably work.

Yes. This base works well. However I always lay umbrella down when there is a storm.

yes I have used it on two different rectangular umbrellas - the weight works well. However, while it will stabilize the umbrella totally - it does not make the umbrella wind-proof. Most of these umbrellas have large amounts of plastic in the mechanism and in the joints. Especially the ones from China. My umbrella was caught in a swirling cross wind and twisted itself to destruction before i could collapse it. It totally stayed upright, and never swayed, but definitely twisted on it's own axis. Beware of this issue as while it is repairable with some effort, it's not a joy on a hot summer afternoon when the umbrella (wind or not) is now useless. Lastly, if you choose, as I did to fill the base with water (and a dose of bleach to keep down any mold) please remember to empty it and store it before freezing. Too heavy and bulky (even with the wheels) to move in any hurry and I'm sure freezing would cause it to burst. I almost lost mine this week here in Connecticut. While it's unsightly, it's effective at what it does. I'm still working on some attractive covering for it. Hope this helps a bit. Dee

Yes they do, and are available on the actual UV Blocker website. http://www.uv-blocker.com/umbrella-holders.html

Any type of metal or plastic base would work for this. It is a fairly light umbrella.

They work fine with my 40" umbrella and flash so I don't see why not...a small part from the bottom that you use to hold the scew in fell out on one of mine though but the other has held up just fine and I've used them for a good bit so I say it's work the $

I only use these with Speedlites so I don't really know, but...I wouldn't try it. I think the heat might be too much. The cloth of the umbrella could get too close and start to burn from the heat.

If the balusters are smaller than 2 inches the umbrella mount will clamp to it. I'm not sure if the aluminum can handle the additional weight or wind pressure. I do not have another option.
