Costco has a very close clone to RaceDeck. I dont think you can get all the different colors and patterns like RD, but they do come in black and white.
Ive seen them on the website and at the local Costco
I have 2 long hooks along the wall that are screwed into the studs. Id say there 6in long with a small lip on the end. You can get them at the big home improvement stires. My ladder hangs horozontal and high on the wall, never notice it when it's there!
