The rocker lugs on these caps and plugs allow for easy gripping, so you can quickly close off fire hydrants and washdown equipment. Tighten with a hook-style spanner wrench (sold separately). Caps and plugs are brass for good corrosion resistance.
NH/NST (National Hose/National Standard) threads are only compatible with other NH/NST threads. Chicago Fire Department threads are only compatible with other Chicago Fire Department threads.

Quick-Access Caps for Pin-Lug Fire Hydrants

These caps are the fastest way to access fire hydrants and washdown equipment. They have a piece of metal with eyebolts that loop over the pin lugs of the hydrant and are kept in place by nuts. In an emergency/when the hydrant needs to be accessed quickly, the end user can then break the metal (ex. hitting it with a wrench) to access the hydrant port. Caps are aluminum, which is lightweight with good corrosion resistance.
