Are these strong enough for downriggers?

Depends on the Gunnal of the boat and how you mount it, if it's thin put a suitable backing plate below, otherwise yes the holder is.....

They are only as strong as the backing plates you install. I bolted them down with 1 1/2 washers on the under side to spread out the pressure. I very much like the quality of mine.

The rod holder themselves are heavy duty. I would say the limiting factor would be the glass you are putting them in. If it is thin you could back it with something I suppose. I use mine for trolling stretches for stripers with no problems, but I don't have downriver a on the boat.

They are most likely strong enough unless you are putting stuff in them that is too heavy in the first place. As for stacking, that's a great idea, but not sure if they will stay stacked-unless you wire them together.

Yes, I believe they will. You might want to use more of them closer together to help distribute the weight a little. They are easy on, and easy off.

I actually used them on a very heavy miter saw stand that gets dropped off the back of the truck onto the ground and they have held up well but I can't say how they would do on a mower. They are tough!

I do not believe they would support the claimed weight that way. There is only a rolled metal lip holding the bearings in. Like one of the other reviewers said, they are cheap and might hold light work. I would not want to stand underneath to test it though.

I'd say yes. You can adjust the strength according to your needs. Certainly worth a try.

I don't know if these would be strong enough...but why not use brass grommets?

I would say yes to the wind, but not sure about people pulling on it. They are pretty strong, but flexible enough to break under extreme loads.. Sorry not much help

Yes they are strong. Normally, only 10-15 mmHg or 15-20 mmHg are available over the counter. And these certainly provide 20-30, which used to only be available to trained fitters or medical professionals. So, beware these are tight, and a beast to put on.

I don't know if they're strong enough. They're not padded. Probably would depend on the weight of your dog and the sharpness of the rocks.

No, they are not spring loaded. Would be helpful if they were. Mine are still a bit too stiff for me.

To be honest, these probably aren't strong enough. I bought the high resistance ones and they weren't enough.

Not sure what you mean by "on fabric." If you use them to attract a metallic object like a political button through a sweatshirt then yes they are strong enough.

I don't think they have enough strength for that use. I have used them to lift up a painting over a flat screen tv. The painting is larger than the max cabinet dimensions in the specs and the lifters needed to be replaced after three years.

I think so. I used them for the spare tires on my trailer they fell apart after one use. They are too big and flap in the wind until they fall apart

I think so they seem sturdy enough. I would be careful when using on a bipod so it doesn't start twisting on the tube, but they are strong enough.

They glide just fine under load. In my application they were loaded with about 200 lbs. one thing you should expect is sagging. With your load at full extention expect about an inch of sag at the far end.
