For more than 40 years, we've been quietly manufacturing casters millions of people use everyday. Trio Pines offers better quality, better selection, better pricing and better service nationwide from our three company-owned warehouses and sales offices across the country. From the lightest duty casters which hold a few pounds, to heavy duty models with capacities over a ton-and-a-half -- and some 30,000 other casters in-between -- Trio Pines offers the best value of any caster company.
