The year was 1993 when the idea of ​​an inflatable air wedge concept was invented by a Danish carpenter. He worked on a job site where he struggled to install large and heavy mahogany windows. His idea was: air underneath is both powerful and accurate! And that was the birth of the invention of the now world famous WINBAG. WINBAGS are typically used in harsh environments and therefore must withstand lifting, leveling or adjustment while operating at full capacity and without degradation.
