If you want to buy Duallock locally, skip Home Depot; they don't carry it (at least not here in Slidell). Lowe's usually has a bunch of long, wide rolled-up strips in stock at a good price. Lowe's also carries a much wider selection of "hobby hardware" that we've managed to use on our robots for sensor mounts and so forth.

In the interest of full disclosure: I have owned HD stock in the past, but never Lowe's. My investment club sold all of our HD because the share price was even higher than the (very respectable) earnings could support. I still shop at HD about twice as often as Lowe's, though they are essentially across the street from each other.
