The McDavid Carpal Tunnel Wrist Support The McDavid Carpal Tunnel Wrist Support is a lightweight brace specifically designed for wear by patients with Carpal Tunnel Syndrome.

To put on the wrist support undo the Velcro straps and slide your hand in placing the thumb through the circular cut out. Adjust the straps to fit. A supportive splint is featured within the brace to immobilize the wrist.
