As it was 100 years ago, Cayce Mill Supply’s commitment to service is our foremost priority. Clinton H. Cayce founded Cayce Mill Supply Company in 1919 selling everything from milling supplies, leather belts, pipe valves, and even explosives. Now through five generations of the Cayce family, Cayce Mill Supply has refined its product offering to the channels of electrical, plumbing, HVAC, tools, and industrial supplies since the 1930’s.
