You obviously like a tidy workshop that looks smart, treat yourself to some plastic end caps off ebay for your box section, would finish it off perfectly....touch of my OCD showing there
I certainly like and want a tidy place, I've been putting up with falling over a complete mess for years which really bugs me and I'm now making a concerted effort to sort it
I kept the end caps open for now as not sure what to do with them. End Caps are a good idea as temporary, I have visions of using them to slide things in such as extension tables and the like.
