Those are neat!
You may inspire me to get my can off the couch and do something constructive yet today. 4 am nights take a lot out of me these days.
(Actually I blame it on the load-in/load-out...we carry LOTS of stuff!

)
Speaking of cable boxes...I use milk-crates...that way the small stuff falls out...never to be seen again.
Sort of like a self-cleaning oven!
