Also, check out the link in post #14 that I cited, it shows the device close up and might give you a better idea of the mechanics of how it grabs. I don't own a [words=http://www.mattersofsize.com/forum/showthread.php?83577-Length-master-official-order-thread-now-shipping-06-16-2014!!!]Length Master[/words] but I tried to make something as close as possible to it, so I assume it works similarly. The device in the pics on this post is another device, with a similar design (minus the handle, and with holes to use it on my Static Stretcher base). On the first one with the handle, you can see that I attached a hook to the front of it and tried to hang with it, but the weight just wanted to slip the device off. That's why I use the sock instead because of it's ability to redistribute the pull.
