We just received our latest shipment of flexible gooseneck tubes and they look great! With this batch of goosenecks we are introducing a new slot-cut addition on the end adapters. These slot cuts allow you to grab the ends of the gooseneck with a wrench to prevent turning while you tighten the 3/8″ screws. Improved Flexible Gooseneck Tubes Now with Slot Cuts These slot cuts are available immediately on our 18″ Heavy-Duty gooseneck arms and will eventually be introduced into our 9″, 18″ (regular) and 24″ gooseneck designs as we deplete our existing inventory.
