Catrike Flag Grommet
This handy little grommet fits into your Catrike flag mount and grips your flagpole, keeping it from falling out. It's that simple! It wedges into the upper window in the flag mount and grips the pole. It gives a nice amount of grip, enough to keep the pole from bouncing out but not so much that it's hard to get the pole in and out when you want to. Super simple and super effective.
Flag mount not included.
