About
Brock String Deluxe Cordlock: Professional Vision Training Tool with Spring-Loaded Beads The Brock String Deluxe Cordlock is a 20ft/6m vision therapy instrument designed for convergence insufficiency treatment and binocular vision training. Unlike traditional Brock Strings, this model features 3 spring-loaded beads that remain securely in place during therapy—eliminating the frustration of bead drift caused by cord stretching or angled positioning. Setup is simple: hold the blue stick end near the nose tip while anchoring the loop end to a fixed point like a doorknob. The ergonomic handle design reduces user fatigue and keeps focus on the exercise itself, not on managing the string. Ideal for clinical settings, vision therapy offices, and home-based vision training programs. Includes detailed instructions for proper use. Single unit.
