Booster lines require which lug type to reduce abrasion?

Booster lines require which lug type to reduce abrasion?

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

Answer: (B)

The need is to minimize wear where the booster line moves against the lug, so the design should shield the contact surface. Recessed lugs create a pocket that the line sits into, keeping it away from sharp edges and spreading contact over a broader area. This reduces friction, edge loading, and heat buildup, all of which drive abrasion. Other lug styles tend to put more projection or exposed surfaces in the line’s path, increasing the risk of wear.
