The Rolyan AlignRite Enlarged Wrist Support gives support to the wrist yet allows fingers and thumbs to move freely. For ventilation, the cotton-coated rubber fabric has an open weave. For the right support for each user, there are notches that can be adjusted. It is designed for a larger forearm than the original Rolyan AlignRite Wrist Support. It has a universal fit, wrist circumference of 6” – 8 ½” and mid forearm of 10”-14”.
