Product Description

2 1/2" (63.5 mm) Aluminum NST Plug & Chain threads to fire department connection (FDC) inlets to prevent dirt, debris, and garbage from blocking a building's water supply during an emergency. While brass FDC components have been a target for metal thieves, this aluminum-made assembly is less susceptible to theft while still protecting threads and system components from moisture accumulation and damage.

This 2 1/2" (63.5 mm) Aluminum Plug & Chain utilizes National Standard Thread (NST), found in fire protection systems throughout the United States.
