Acme Duplex™ and Acme Twin™ Window Sash Balances
Acme Duplex™ is the authentic sash window balance. Invented and patented by our founder Aloysius F. Mantz in 1926, the Acme Duplex™ window balance continues to be the standard for double hung windows throughout the U.S.
The traditional Duplex™ balance is manufactured today in San Bernardino California, using the best materials available, as originally specified by architect and engineer Mantz.
Acme Duplex™ balances, Acme Twin™ sash balances and Overhead Mortise Tape are used in manufactured windows, and are available in hardware stores throughout America. We are proud of our heritage and continue to insist on top quality.
We invite distributors and retailers to look for the Acme Duplex™ trademark on each box, and to be sure to accept only authentic Acme window sash balances.
