If anyone is working in a tight space, I recently found that wall control makes pegboard that are only 8in wide. [1]. They're made to be horizontal so if you flip them some of the fancy accessories that rely on the horizontal slats won't work, but the pegs are still fine, and it's a good way use otherwise wasted space on really narrow walls and corners. https://www.wallcontrol.com/8in-x-32in-horizontal-galvanized...
Seville has a 24W x 18D x 66H metal cabinet with pegboard sides, https://www.sevilleclassics.com/collections/cabinets-1/produ...
