The ProFlex 1051 Mesh Back Support Brace 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. This back support features breathable polyester mesh and a contoured, ventilated lumbar pad for light compression and support––helping to reduce strain and address chronic back pain. Not only does the polyester mesh allow for maximum airflow, but the material also absorbs sweat and wicks moisture away. SIZING To choose your size, use flexible measuring tape and find the circumference around your body at your belly button. The support should fit snugly around your hips with the front of the support two-fingers width below your navel. An easy-to-use hook & loop closure keeps the belt securely fastened while in use and can be worn over or underneath clothing. HOW IT WORKS ProFlex Back Supports provide lower back support and abdominal support for lifting heavy objects. Tightening the back support Power Panel 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. When not lifting, be sure to loosen the belt. Power Positioners™ help keep Power Panel belt in place, instead of dangling off of the support. Great for airport luggage handlers, warehouse/distribution employees, material handling, construction crews, maintenance, assembly/fabrication, landscaping/grounds and jobs that require heavy lifting. We cannot guarantee that wearing a back brace will prevent workplace injury or be a cure for lower back pain, but when used properly these supports will provide extra lumbar support, promote proper lifting techniques, and help you through a workday of bending, twisting, and schlepping. Rest assured; we got your back.
