Use those as replacements for damaged, lost or worn bushings for your antenna mounts. Fits a 1/2" hole with the center size being 3/8". Can also be used for making feed thru insulators by using a 3/8" metal pass thru for your antenna line. These are a little thicker on the base and deeper on the bushing part that goes in the hole, making these a heavier duty bushing than our other bushing sold in the 5-pack. Hard to find!
