Designed to fit the PL-259 or UHF Male coax connector. Designed with a snug fit for gripping power on the connector (Hint - if too tight for your fingers, use a hair dryer to soften cap).

. Made of black flexible vinyl. Designed primarily to keep out dust and contaminants, they are not intended to moisture proof a connector without additional weather wrapping. 

Note - for thicker UHF Male (ie: LMR-600, etc) use our slightly larger cap.
