These reducers are used when installing a PL259 connector on CB coax to reduce the size of the connector to fit the coax better. The end result is a more stable connection to the coax that is less likely to wear and/or break over time. There are two sizes of reducers (selectable above), one for RG58 coax and one for RG59 coax. There is a slight difference in size for the cables, so be sure to choose the right one!

For RG8X and RG59 coax cable, you will want the KUG176.

For RG58 coax cable, you will want the KUG175.
