Brock String with Deluxe Cordlock — 12ft/3.6m Length with 5 Spring-Loaded Beads.

Traditional Brock Strings struggle with bead slippage, especially during upward-angled exercises or extended therapy sessions. This deluxe version features 5 spring-loaded beads that stay firmly in place throughout treatment, eliminating frustration and ensuring consistent results.

Hold the blue-stick end near the tip of your nose while securing the loop end to a fixed point like a doorknob. The ergonomic handle design keeps focus on the exercise, not on managing the string.

Ideal for treating convergence insufficiency, binocular vision anomalies, and suppression disruption in clinical and home settings. 12-foot length provides ample working distance for most vision therapy applications.

A reliable, professional-grade tool trusted by vision care practitioners.

Instructions are not included and should be obtained from your eye care provider. Ideal for clinical settings, vision therapy offices, and home-based vision training programs.

Single unit.
