Rocketry Works' BT-70 coupler fits smoothly inside the BT-70 airframe tube or the BT-70 slotted airframe tube, allowing you to join two sections of tube as a bulkhead or a coupler. The 4 inch length gives plenty of overlap for a secure and straight joint. Some light sanding may be needed to achieve the desired fit inside a BT-70 body tube.
