Our smaller Hummingbird Feeder Stopper with Ball Bearing,HBF-1516BB, has a conical shape. The rubber stopper has a diameter of 11/16″ at the bottom and 15/16″ at the top. Tube diameter is 1/4″ and 2-1/2″ long. Overall length 3-1/4″.
TIP: Always fill your feeder completely full with cool nectar. Insert the stopper and invert quickly to avoid any air entering the feeder. Tube feeders operate on a vacuum principle. Only if the feeder is initially filled completely full will the vacuum form!
