The ProFlex 1675 Back Support Brace not only promotes proper lifting techniques but also offers versatile hot/cold therapy. ProFlex back supports are designed to remind workers of proper lifting techniques while also enhancing the body's intra-abdominal pressure, moving the stress away from the spine. Featuring 480D spandex body material with a v-shaped design, this back support brace provides a firm level of support and also features mesh material on the backside for increased airflow. Rubber track webbing stays are sewn onto the interior to help keep support in position and prevent it from riding up. COOLING/WARMING PACK: Included with each back support is a reusable cooling/warming pack for soothing pain relief. The pack can be activated in the fridge or freezer for cold therapy or warmed up in the microwave or boiled on stovetop for hot therapy. Cold therapy targets inflammation, swelling and muscle spasms, while heat therapy targets muscle aches, tension, stiffness and chronic pain. To install, slide the pack into the back mesh pocket of back support and secure in place using 2 button tabs. ProFlex 6275 Reusable Hot/Cold Pack Replacement (2-Pack) also available. 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. Adjust the suspender straps to fit securely on your shoulders without causing tension. Turn it into a back support belt by simply detaching the suspenders from the belt. 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. Detachable and adjustable suspenders keep support on standby until the next lift and 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 work day of bending, twisting, and schlepping. Rest assured, we got your back.
