The ProFlex 500 Elbow Brace Strap provides comfortable elbow and joint support on and off the worksite. The soft and stretchable neoprene compresses the forearm to improve blood flow to the elbow, aiding in pain relief and joint flexibility. This elbow support is a great solution for reducing pain and increasing productivity. This comfortable latex-free elbow brace is made with a durable four-way stretch neoprene that does not limit range of motion. A secure hook and loop strap allows the wearer to adjust to desired support level and fit, while the contoured ambidextrous design allows for wear on either arm. To determine size, measure the circumference around the widest area of your forearm (just below the elbow). For best fit, the support should sit about 2-3 finger widths below the elbow crease. This elbow support is designed for workers, athletes or anyone needing additional support for injuries such as tennis elbow or golfer's elbow.Note: This is a non-returnable item.
