29mm Carbo Swivel
Single Bullet Block


The 29 mm Carbo block is like jewelry. This compact block is extremely strong. Use our miniature Carbo as a mainsheet block on small dinghies such as the Optimist, or for low-friction control blocks on any size boat.

Doubles and triples feature U-Locks to hold the swivel in front/side position, or to let it spin freely. The triple’s compact cam arm supports high-load purchases of 5:1 or 6:1. The line-shedding cheek block features a small mounting footprint and drainholes. The low-profile Ti-Lite replaces headpost, shackle, and spring with high-tech line.

Use for:
Traveler controls
Flag halyards
