How do I stack "Boltless" Shelving?

Question

I have shelving units that are "Boltless" I think they're called, anyway they have legs about 3 feet tall with areas where the shelving braces can slide in with built in bolts...I need to doubble the seize, but I can't find a way to do it...Do you know how?

Answer 1

Bolt-less shelves with bolts?  Hmm.

Double size in height:

Usually there are adapters that slide around the legs like collars, allowing the legs to stack without sliding off one another.

Double in width:

Try staggering the shelving, (almost like a brick pattern) so that the middle set of legs is shared between both sides of the shelf.

Hope that helped, you might add some better details...
