Which lug type is usually found on couplings of old fire hose and resembles small pegs, often snagging on objects?

• A. Pin lug
• B. Recessed lug
• C. Rocker lug
• D. Extended handles lug

Answer: (A)

Protruding features on hose coupling lugs tell you how they interact with objects in the field. A pin lug uses small peg-like protrusions that stick out from the coupling surface. Because they jut out, they’re easy to catch on objects as you drag or pass hoses through tight spaces, which matches the description of small pegs that snag. This snag-prone, peg-like appearance is what makes pin lugs the best fit for old fire hose couplings. Recessed lugs sit flush and are less likely to snag, rocker lugs have a different curved form, and extended handles lug adds handles for leverage—none of these match the “small pegs that snag” clue as well as pin lugs.
