Deluxe Cordlock Brock Strings, 20 ft with 3 Beads702806
Beads that fail to stay in place are the bane of traditional Brock Strings. The cord stretches or the exercise requires an upwards sloped string and then the beads start moving. This product solves the problem by using 3 spring-loaded beads that are guaranteed to stay in place!
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, the cord lock versions are used for the 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.
