If you make boxes, frames or something like that, the strap clip will be a good storage tool for your collection. This one is particularly handy as it allows you to clamp various corners, so you're not limited to just right angles (although it does include some positioning squares that will come in handy when you're dealing with right angles). After testing. everything, I'm happy to report that it works pretty well. The strap clip is easy to use and gets the job done and the positioning squares are really square. Being all plastic it might not be up to the toughest of conditions but for my light to moderate use it's more than adequate. The only thing I don't like is that the strap itself can be a bit uncomfortable. I've seen several belt clips with coils to keep the unused portion of the belt under control and I wish this article had such a device (and I've added making one to my to-do list as it is should) . that would be too difficult). Otherwise I couldn't be happier with it.
