I have a crawl space under one of my staircases, so it's triangular in shape. Dimensions: 32" W x 30" H x 60" D (depth at bottom). As you can see in the photo, it's separated by a 2x4 in the middle. I use it to store paint and other home improvement related stuff. The boxes are heavy and pulling them out is a pain, so it's hard to reach stuff that further in. So I am thinking of putting in some sort of slide-out shelf on either side of the 2x4 so I could pull it out. Similar to pantry roll-out cabinet except it has to be much heavier duty and bigger (more or less the full 60" of depth) than anything for kitchens. Problem is, I can't find anything that's would fit the bill. I find either something light-duty for kitchens or industrial roll-out solutions that are way too massive for me. Would you recommend something? I can try to build it myself from proper parts or buy a ready-made solution, although I am trying to keep cost down. Obviously, it does not need to be pretty, but it does have to be solid enough to hold a fully pulled out shelf of ~60" in length loaded with a lot of weight. Thank you!
