Query: Perfect for those skinny iron railings

This is officially one of the best pot holders I've ever purchased. The white one, which is the same length as the black, is constructed of thicker components making it a bit sturdier than the black holder (opposite of the round HoldAll plant holders). This fits my iron balcony railing perfectly, without tilting forward or warping under the strain of my heavy planters. Unlike all those I've seen in stores (you know the ones, with the annoying screws that only fit wood railings) these are made for those black iron fences with ~8" fence spacings. I originally purchased my from OzBo (now out of stock) for less than $7.00 around 6/21/09 so I would recommend looking around online for a deal that is less than the current companies pricing. I love these so much I'm currently doing that same search for a few more!
