Our new innovative and patented design by STRETCHAIR™ has the potential to revolutionize the construction industry! STRETCHAIR™ expandable air hoses save time, reduce fatigue, and last longer. Conventional air hoses suffer at least one of the following drawbacks: too heavy, kinks easily, do not perform well in cold weather, or are not very durable. The NEW expandable air hose design by STRETCHAIR™ overcomes all of these challenges and outperforms other air hoses. STRETCHAIR™ expandable air hoses are lab and field tested.
