Booster lines typically have couplings with what type of lugs?

Booster lines are specifically designed for ease of use and quick deployment during firefighting operations. These lines often feature couplings with recessed lugs. The recessed design helps to streamline the coupling, making it less likely to snag on obstacles when being pulled or deployed. This design is particularly beneficial in tight or challenging environments, ensuring that firefighters can maneuver and operate effectively without impediments. Recessed lugs also provide a cleaner appearance and minimize the risk of injury to personnel handling the hoses, as they reduce sharp edges that could cause cuts or abrasions. This coupling type supports the essential function of booster lines, which is to deliver water in quick response situations while maintaining firefighter safety and efficiency.
