For more than 120 years, Caldwell has created quality spring balances for window manufacturers around the world. Our products are everywhere from homes to schools, office buildings to hotels, even the United Nations Secretariat Building and the Empire State Building in NYC. It all began in 1888 when Allen Boucher and William Caldwell formed a company to supply window products to hardware stores throughout the Northeast. At first, Caldwell’s core product was a clock spring counterbalance that revolutionized the window construction process and firmly established Caldwell in the fenestration industry.
