The ProFlex 1400UN Universal Size Back Support Brace provides lower-back and abdominal support for lifting heavy objects, while accommodating nearly any waist size. Universal-fit design accommodates waist sizes ranging from 25 to 58. Non-conductive polypropylene stays and comfortable-stretch 280D spandex body ensure long-lasting integrity. Before lifting heavy objects, simply tighten the support belt to enhance the body's intra-abdominal pressure; and after lifting, just loosen the belt to achieve a wider range of motion. Secure-fit, interior rubber-track webbing prevents the belt from riding up when bending or lifting. Innovative Power Panel Positioners keep the tension bands close-to-hand, making it easy to get the desired level of tension. Adjustable, detachable suspenders allow the wearer to tailor the shoulder-fit to his or her unique needs. For best results, the support should fit snugly around the wearer's hips, with the front of the support two-fingers below the wearer's navel. When worn correctly, workers can easily maintain the proper posture for lifting, while achieving the extra support required to safely complete the task. Easy-to-use hook-and-loop closure keeps the belt securely fastened while in use. Brace can be worn over or underneath clothing. Machine washable—machine-wash cold and air dry.
