How do I know which size to order?
Measure the cast from end to end. THE CAST PROTECTOR needs to cover the entire cast. Chose the size which will adequately cover the cast. It is best to measure the cast length and the largest circumference. Remember the pad can be removed from the cover for trimming to the exact size needed.
THEREFORE, IF THERE IS A QUESTION, BUYING THE LARGER OF TWO SIZES IS SAFER.
The smallest size is the 10-inch size designed to fit the smallest players. It is 10 inches long and 12 3/8 inches in circumference. The pad is 3/8 inch thick. (With the pad in the cover the device measures 5/8 inch thick.)
The 11.5-inch size fits preteens, women and smaller males. It is 11.5 inches long and 13.5 inches in circumference. The pad can be cut down for smaller children. Keep in mind that the 1/2 inch thickness is used so it will seem bulky on smaller children.
The large 14-inch size is based on a 6′ tall 220 lb. male and should fit most larger individuals. It was made with football linemen in mind. It is 14 inches long and 15 inches in circumference.
With the THUMB PROTECTOR, one size fits all.
