Heavy Duty Wall Mount Storage Shelf

Does the 4’ supplemental (lower) rack require using just with rack 6001, 4 ft. or can it be used with the 8 and 10 foot racks?

Mixing it up would work for me since while a 12’ section would work high up, I don’t have room for a similar lower shelf for the entire length. Fitting one or two 4’ lowers would work great. The expense of tying three 4’ uppers would get a bit pricey.

If you look at the ProRack Megabundle also offered with this deal it’s exactly what you’re asking for.
