Bought the 20”X20” unit to add more shelves to the wasted space in my linen closet. Liked it so we’ll I purchased this 18”X18” unit for the pantry!
They both work great! In fact, I now plan on getting another one for the guest bathroom linen closet.  They are very well made, the perfect size for fitting into closets  spaces where you need a little extra shelving￼  they are attractive too!!
Highly recommend them.
