Goodnite 702906 Deluxe Cordlock Brock Strings

During therapy, the end with the blue stick is held near the tip of the nose while the other end with the loop is hung to a fixed point like a doorknob. Our new handle looks sharp and helps the user focus on the task, not holding the string. Just like the traditional Brock Strings,, Cord Lock versions are used for treatment of convergence insufficiency and other anomalies of binocular vision as well as to disrupt suppression. Each pack comes with instructions for each Brock String.
