A coupler allows two lightsaber hilts to be connected and form one big staff. Our couplers are compatible with the VHC system that is used by all our Dueling sabers.
If you have two of our dueling sabers that you want to connect to each other, add one of those couplers. You'll have to determine if you need the internally threaded or externally threaded one. In doubt ask us on the chat and we'll check it our for you.
Usually it fits right in between the grip and the pommel. Some of our sabers already have a coupler included, be sure to check the description.
If you have any questions about our products feel free to reach out to us through the chat, we speak english and french.
