Question: What material is the frame made out of? Steel or Aluminum? And how much weight will it support? Thanks!
Document: I only use this to support a 36&#34; wide paper for food photography. Built quality is just OK. The stand already made several holes on the bag.
Surprisingly for the price, it's well made and very portable. **  Update 07/04/12  **I've added a photo to the gallery of my informal studio setup with 2 crossbar sections and my home dec fabric draped over the support system.
I was looking for a portable background support system to use at home as well as on location to do some portrait photography work. I looked at several models and read many reviews, but could not decide on one. There were some models where the support bar would sag under the weight of the fabric or paper.I asked my brother (a fellow photographer) if he knew of good system. He suggested Cowboy Studios.
Other than that, I still give it 5 stars for how much use I get out of it.
Pretty good quality for the price, I was a bit concerned it would be cheaply made, but it wasn't at all bad! Perfect for our in-house photo studio.
It was a little bit more than I wanted to spend but of course still a great price and I'm really impressed, surprisingly light for such sturdy stands. I couldnt be happier and I love the guys (and gals) at Cowboy, they always take care of me. Thanks guys!
I set up a studio in a garage and this stand has proven to be more than adequate for the job.I've had three cloth backdrops hanging all at once, flipping them over to the one I wanted without any problems.The stand is light weight, yet was able to hold the cloth without sagging or drooping.
Just got this and so far this thing is amazing. It comes in a great carrier with individual slots for each pole and stand. The stands and bar are super durable and lightly spring loaded. Everything about this stand screams high-quality and I would expect it to cost way more. I wasn't expecting much but think this thing is great!
This is a wonderful background support system. Very good quality, and easy to setup. I wouldn't hesitate on this background kit.
Yeah, I just got mine in the usps, mail today, surprisingly, it was very easy to set up. Me and  buddy of mine, set it up in about ten minutes. And yes, its quite stirdy. I was really impressed when I got it up and going with a baack drop, took a couple of test shots, and it holds its own.One of the best pieces of Photographic equipment ive ever purchased. And huge thanks to amazon, for prompt delivery.
