2501 Adjust-A-Plug
Here's an inexpensive protective plug for swivel connections up to 2 1/2" in diameter. It features two adjustable metal plates installed in the back of the plug, that can be easily mated with your local thread. Once adjusted to size, the metal plates are locked in place by a central metal bolt. The plug can be easily removed with a fire department spanner wrench. The plug can be re-installed in place by fire department personnel after shutdown. Supplied in standard red.
