So I have been chewing on this for a while now and thought I would try my hand at a simple, yet effective, easy to use way to keep the drawers from flying open during travel. Bought some cheap self-adhesive (VHB) hardware and some small bungee cord. Voila... I hope it works. Easy to apply cordage and when removed just toss in the drawer. I bent the lower ones down to almost flush so hopefully they won't snag someone. The top ones can be used as hooks or left alone when not in use.
