Simple yet brilliant design. Since my original telescoping crossbar only reached 6'6", I went looking for one that wasn't too costly and could go up to 10' wide and not bow in the middle. After much research, I ended up here and though shipping was almost as much as the crossbar itself, this product is worth every penny. There is even little runners inside the tubes that allow the pin to automatically go through the hole in the connecting tube and also prevent excessive wobble/play. Very solid yet light. If I had known about this company before, I would have bought my background stands here as well !
