The name Gretsch-Unitas is a combination of the name of the company founder Viktor Gretsch and his UNITAS metalware factory where the successful Unitas Horizontal-Pivot window hardware was manufactured. The patent for sliding door hardware was registered as early as 1924 and in 1958, with the invention of the Lift&Slide system and subsequent further development in 2017 to a fully barrier-free Lift&Slide door, the HS ePOWER, Gretsch-Unitas group set standards that have had a profound effect on the market up to the present day.
