Rhino BaseMate 18" Umbrella Base Weight – Fits Offset, Cantilever & Outdoor Patio Umbrellas – Detachable Design – Black – Easy Setup

Seemingly strong fabric, even when filled with sand. Did not feel like it would rip when I had to move it multiple times around the yard when finding the right place for my umbrella. Like other commenters, I added one sandbag (the whole bag, not loose) into each of the two weighed bags. There's handles on the bags to make moving and positioning them easier. There's also hook & loop on the side with the pole notch to attach each bag to each other. This brace weight will work great for most round bases. However, for a crossbar base, you should do the following, to get a sturdy and solid foundation. This assumes your crossbar base has the bottom lips where you would normally attach them to the ground with bolts. First, get yourself some concrete square step stones. At minimum, get two. But since you're there, get 4, one for each side. They're cheap. Put each of these on top of the lip of the base. Now you've made yourself a nice movable base. Next, put these bags on top of the crossbar. If you've filled the bags with 50lbs of sand, along with the stones you'll have about 300lbs altogether keeping this thing down. And moving won't be a problem since you'll just need to move 50lbs at a time. Pros - Bags seem sturdy and don't look like they will rip. Time will tell if the weathering will cause these to disintegrate - Handles on each side make carrying them and moving them a cinch. - Big enough not to cause any problems when filling with 50lb sandbags without taking the sand out Cons - Made mostly for round bases, but can be repurposed (see above) for cross bar bases - If you have a large cantilever umbrella, the 100lbs that this can fit (2 50lb bags) may not be enough. See above for tips on reinforcing with step stones. Overall, this fit my purpose. We were hosting a little kids party and I had to make sure the umbrella stayed put even if some sugared-up kid decided to mess with the umbrella. The combination of this weight and the stones made sure of that.

Why did you pick this product vs others?: Our area frequently experiences very high winds that blow the covers right off our patio furniture (fishing the sodden covers out of the pool is a special kind of "fun"). I got these to weigh down the the patio dining table cover, and they are just perfect. We filled them with 25lbs of sand each (note they can hold much more), and placed one at either end. The form factor isn't right for our umbrella base, and I had initially thought a cloth weight would never stand up to our desert heat anyway, but these are MUCH thicker and sturdier than, say, Sunbrella fabric, so after seeing and using it for myself, I think they'll stand up to just about anything.

Worked fine. Put full sand bag in. Tight fit but its holding my umbrella.

We absolutely love these weight bags. We use them as counterweights for our event rentals business. We have used them consistently for nearly 5 years now and could not be happier. We fill them with water softener salt pellets instead of sand to avoid the mess. Highly recommend these & love that they come in a pack of 2!

The bags are great. I split a bag of sand between the two and stuck them around umbrella pole. Looks good!

We just got the weighted base, so I don't know how long it will hold up. the the bags and stitched handles appear to be sturdy. The bags were also easy to fill because of the full length zipper openings. I also like the fact that there are two sections, rather than just one full weighted base, which would be very hard to move without having to remove the sand. The main reason I didn't give this a better rating is that the description of the product said it could hold 100 pounds of sand. We could only squeeze a total of 80 pounds of sand into the bags. Since our overset umbrella instructions said that 100 pounds of weights were needed to keep the umbrella from tipping in any windy situation, we now have to find a way to add some more weights or blocks to keep the umbrella stable.

This is such a great idea. Very sturdy with a zipper. 2 pieces so you don't have to disassemble the umbrella. You can fit a 50 lb bag of sand in each piece. These will last for a very long time.

Used it to add xtra weight to umbrella base. We will see this spring if it stands up to winter
