Do the cabinets butt up to each other or is there a spacer between

Will butt nicely: used 20mm lg, M6 Furniture Joint connector bolts w/barrel cap nuts Put 4 per box a few inches from corners to pull cabinets tight.

Dear Bren, thanks for your question. Yes these cabinets can be butt up to each other and you can use filler strips to cover up the spaces in-between if needed. We look forward to hearing from you.
