Brand: Jiffy-tite
This 2-in-1 rubber dust cap can protect either a 2000 Series Jiffy-tite socket or a 2000 Series Jiffy-tite plug from dust and debris when disconnected.
The clever design fits snugly over a socket collar, but a special indentation deep in the bottom lets it snap onto the end of a plug. When installed properly on a plug, the entire plug is covered, ensuring a clean connection. Sold individually.
