By establishments it ranks 1st of the 4 codes at this level within Hardware, and Plumbing and Heating Equipment and Supplies Merchant Wholesalers, with 32.2% of them.

Between 2018 and 2023 the number of establishments grew 5% and employment rose 32%. The 2018 count used NAICS 2017, so part of a large move can come from codes being redefined rather than from businesses opening or closing.
