The Universal Quick-Release Coupler is engineered for seamless compatibility with 1-inch diameter 2-in-1 saber handles from the Apprentice Tier Collection. Before purchasing, please confirm whether your saber handles use male or female threading to ensure compatibility and a proper fit. Installation Installation is quick and straightforward: Remove the bottom caps from both saber handles. Attach each half of the coupler securely to the exposed threads. Ensure both halves are firmly tightened before use. Connecting the Sabers To connect your sabers: Align both handles. Insert the spring-loaded coupler stem into the opposite half. Continue until the ball-bearing locking mechanism securely clicks into place. Disconnecting the Sabers To disconnect: Press both saber handles inward to release tension on the coupler. Pull the central spring section outward. Separate the two saber handles. Rotational Movement & Blade Alignment The integrated ball-bearing system allows the connected sabers to rotate smoothly during use. Because the coupler is designed to allow rotational movement, blade alignment cannot be permanently fixed and may require occasional manual adjustment. This is an intentional feature of the design, providing fluid rotational movement while maintaining a secure connection. Compatibility Important: The Universal Quick-Release Coupler is only suitable for Apprentice Tier Collection sabers. Please confirm the threading type and saber compatibility before placing your order. Important Notice Accessories and service add-ons are final sale and are not eligible for return or exchange. We strongly recommend confirming compatibility before purchasing. If you are unsure whether this coupler is suitable for your sabers, please contact our support team for assistance before placing your order.
