What are the "jail bars" made out of? Are they metal or plastic? If they are plastic, are they durable enough? Do they rattle?

The jail bars are metal. The cage is very sturdy. Sullivan seems to really like it, when I ask him if he wants to go on the porch he runs immediately to the cage.

the jail bars are made of metal covered in plastic. They do not make a sound. My 3 cats love it.

The bars themselves are made from aluminum. the brackets on the end that clamp the rails to the bars are made from plastic.

They're plastic and very sturdy. I take two little dogs in mine. One is 8 lbs and the other is 16 lbs.

Not sure how much weight they can withstand but they are pretty sturdy. They are all metal.

The top is metal (aluminium) and the bottom is hard plastic. Overall it is very solidly built, no rattling at all.

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.

They are very sturdy. I would say some kind of metal. They are not cheap feeling at all. I love them.

They are plastic. I know my nephew loves it, but if you want more details, ie how durable, etc. just let me know & I'll ask my sister!

They are plastic. But very durable. My son and daughter both sit in the wagon and we push them around. This wagon is great.

It is a rigid yet bendable plastic. The base is a ring that is not full closed. About 20% gap which. You use to forcefully clamp around a bar. It is not very sturdy, but works well as long as you have it against something... The dashboard for example

The clamps are indeed made of plastic, but are rather beefy in construction. They should hold up as long as they aren't run over by vehicles or clamped to exhaust manifolds or other very hot surfaces.

Metal. I bought three of them, with two of them purchased after I bought the first one. They aren't as sturdy as the heavy duty ones (like you might use in a garage), but for the money and purpose, they do the trick. If I needed another, I would buy again.

Based on the price, and description lacking info on metal tracks I would guess they are plastic. I installed metal tracks and a metal gear box on mine but it is cheaper if you can find one with those options already installed.

They are metal. It is what it is, you can get something sturdier but you will pay a whole lot more. This has worked just fine for us and it was pretty easy to put together.

They are made of a resin type plastic. Seem to be really durable. I only weigh around 150 so I am not exactly heavy. Should be able to handle much more though.

They are plastic. We were hesitant about buying it for this reason, but my son uses it for almost an hour every day and they haven't worn out in the 4 months he's been using it. It is a bit loud, would be quieter if it had rubber wheels.

Metal. Great quality. Had mine for a year and love em. I don't think you'll be disappointed. I weigh 150 and they've held up great
