stickwurm – yes that is drywall corner bead. I just bought an 8 section for $2 at Lowes and cut it to fit. Works pretty well actually. Im sure it doesnt work as well as the cooks system but better than the spinner bait boxes.Its kind of funny – I spent over $50,000 for the boat but, hey, I saved $20 on the spinner bait storage instead of buying the cooks!
