Which lugs are considered the most common and feature a higbee cut for easy connection?

Rocker lugs are the most common type of lugs used in fire suppression systems and are specifically designed with a Higbee cut. This design feature allows for easier and faster connections to be made during the process of setting up equipment in emergency situations. The Higbee cut is a distinctive taper at the end of the lug that reduces the likelihood of misconnection and helps guide the connection into place correctly.

This design is crucial for efficiency during firefighting operations, as it minimizes the time spent securing fittings under potentially stressful conditions. Rocker lugs are therefore essential for ensuring reliability and speed in high-pressure scenarios, making them a favored choice among fire suppression equipment.
