INNOVATIVE DESIGN

When the U.S. Navy asked us to develop a flotation device that would dependably withstand particularly abusive conditions, Subsalve USA produced the 5-ton Deep Ocean Lift Bag, which has unprecedented strength, low elasticity and superior resistance to abrasion and chemical attack. It became our standard Professional Lift Bag design.

  • Each Subsalve product is 100% tested prior to shipping.
