They are quite heavy. Heavy enough I didn't take them on the plane for a photo shoot. I don't know the exact weight. Maybe 2-3lbs.

I have now had two burst while clamped around my backdrop stand. The spring is much stronger than the plastic the clips are made from.

They are not heavy. I thought you can Crazy Glue a fishing line to them with a weight reaching bottom of lake to them. That might work.

You will need clamps. But read reviews for product before you buy. Just sayin'

It is heavy duty. They are not comparable to the plastic Lowe's clamps. Both the orange and silver components in this picture are solid metal on the clamps I ordered.

Not that heavy... I think it's made of aluminum metal. And they require assembly but it's pretty easy.

I am unsure about how much weight your weights weigh, but we had these in the garage and had several things on them; moved to another town and had them in a basement again with many shelves, kids play things, exercise equipment etc; moved one more time and didn't need them sold them at a garage sale, they still looked great and got almost what we paid for them.

The clamps are made of plastic (nylon?) but are pretty tough...I got them for a project that I needed them for which require the clamping on to a circular structure. After many cycles of clamping on/taking off, the clamps have yet to fail.

Do not know exact weight, but they are a bit heavy. I use them for my heavier draw weight bows 50lbs+. For lighter weight use bamboo...Jack

They are not light weight, but you might use some heavy duty Velcro with adhesive. We keep ours on the ground and move them around (with ease) as needed.

I am not too sure they are not real heavy but yet sturdy to hold up to 250 lbs hope this helps you have a good day

i think they were weighted 50 lbs? i forget. I didn't hang anything too heavy but they were fairly large D rings.

I don't know exactly as I returned this product. I do recall that they were not what I would consider heavy.

Not heavy at all, the water pressure is what adds weight. They do work very well.

I'm using them as a support for a shelf over my fire place and not putting anything more than knick knacks on it. I wouldn't put anything heavier than that and a few books. Call it 20 pound load at most.

No not at all. these are quite strong and solid. Weight should not be a concern.

i wouldn't say they're weighted, they're more like resistant with a somewhat heavy feel.
