The Cuff rehabilitation wrist and ankle weight has been proven effective in hospitals for over 30 years. It contours to snuggly fit the ankle, wrist, and even thigh. Its long closure strap assures a secure and comfortable fit even during the most strenuous exercise program. It features heavy-duty materials and double-stitching throughout. The Cuff exercise weights are color-coded, marked with both pounds and kilograms and have grommets for hanging on any peg-board weight rack.
