A: They are a pliable plastic and a small to medium hanging plant basket of flowers n soil is fine. I do wish the circular holder itself rotated.
A: Hi, please email email@example.com for more information.
A: Yes they will work. I used the on mine, no problems.
A: These pieces are designed for Palram Greenhouses and hence fit the groves on that brand's product. No guarantee that they will work in some other situation such as a patio cover.
A: mine did not fit in the groves.
A: Yes they will.
A: Not that I know of-- just the packages of 8 or 10.
A: I have not seen them in larger quantities with at all so I ordered 2 packs.
A: no discount. 10 in a bag
A: I've been able to hang a 6" clay pot filled with potting soil with no issues. Haven't gone any higher.
A: I've had a 10 pound hanging basket on one hanger with no issues. Remember, they are plastic so I'm sure they are prone to break if over stressed. Age, as with all things, will probably also become a factor eventually.
A: I don't know the weight but I have a 3 foot two fluorescent shop lamp hanging on two of these little plant hangers with no problem. You can leave them in a loop or cut them to use them opened. I have an aluminium small greenhouse I use them in.
A: Not much. I hung a wire basket with soil and plants. It weighed maybe 20 lbs. It lasted 1 week and came crashing down. I wouldn't trust it for anything over 10 lbs. Maybe less.
