Ergodyne - EGO11400 ProFlex 1400 Universal Back Support Brace is designed to fit most waist sizes and remind workers of proper lifting techniques. It also enhances the body's intra-abdominal pressure, moving the stress away from the spine for back pain relief. Rubber track webbing helps keep support in position and prevents it from riding up. Spandex is stretchable for comfort and support. Stays are made of nonconductive polypropylene for long-lasting integrity. Adjustable, detachable suspenders keep brace in place. Brace is machine-washable in cold water.
