Features
1. Economy Spandex Back Support is designed to remind workers of proper lifting techniques while also enhancing the body's intra-abdominal pressure, moving the stress away from the spine for back pain relief. Features rubber track webbing to help keep support in position. 
2. Back Supports provide lower back support and abdominal support for lifting heavy objects. Tightening the back support belt enhances the body's intra-abdominal pressure and moves the stress away from the spine. When the back support is on correctly, the worker will have additional support for lifting and is more likely to use proper posture. 
3. COMFORTABLE Contoured high-cut front panel for a comfortable fit
4. NON-CONDUCTIVE Polypropylene stays for long-lasting integrity
5. SUSPENDERS Adjustable, detachable suspenders keep belt in place
