Flashing Beacon - Lens Retaining Clamp [ยง24]
This clamp is used to retain the red flashing beacon lens on top of the vertical stabilizer tip.
Grummanologist Tip The original versions from the factory would generally have screws that became rusty or corroded and made removal of the lens extremely difficult. If you are replacing the bulb in the beacon, examine the retaining clamp at the same time to determine if it should be replaced along with the bulb!
