Great Product
Use them every time I take my truck through the carwash. They keep the water out of the connector.

Good Fit
So far the SO-239 Dust Covers had fit all of the connectors that I have used them on. It's a good idea to get a few extra as spares.

I tend to lose this cap and have purchased numerous caps through the years. I like the stronger steel cap and the internal seal. I also really appreciate the cost and the great service provided by... American Radio Supply. I will continue to purchase this item when needed.

Used these caps to cover an MFJ thru window feed thru connector panel. The internal rubber grommet protects the unused connectors from the outside elements. Highly recommended!
