I've used many different things over the years, but the best I have found has been a regular ACE Wrist Wrap with Velcro. Just wrap it around the entire box call and it cannot move. It also protects from nics and scratches. I have been using the same ACE Wrap for the past 5 years on my Lynch Box and the Velcro is still in great condition. I found mine at WalMart for about 3-5$
