The universal quick-release coupler is engineered for seamless compatibility with all 1-inch diameter 2-in-1 saber handles. Before purchasing, please confirm whether your handles use male or female threading to ensure a proper fit. Installation is straightforward: remove the bottom caps from both handles and securely attach each half of the coupler to the exposed threads. To connect, align both sabers and insert the spring-loaded coupler stem until the ball-bearing locking mechanism clicks into place. To disconnect, press both handles inward to release tension, then pull the central spring section outward to separate them. The integrated ball-bearing system allows smooth rotational movement during use. As a result, blade alignment cannot be permanently fixed and may require occasional manual adjustment. This is an intentional design feature that enhances fluid motion while maintaining a secure connection.
