Nsabers’ universal quick-release coupler fits all 1″-diameter 2-in-1 lightsaber handles. Before purchasing, confirm whether your handles use male or female threading. To install, remove the bottom covers from both handles and screw on each corresponding half of the coupler. To connect, align and push the spring-loaded stem until the ball-bearing lock clicks. To disconnect, press both handles together to release tension and pull out the central spring.
