Harken 2631 Quad 57 mm Carbo Swivel Block

Carbo AirBlocks® are 60% stronger and 30% lighter than our classic blocks.

The nylon resin sideplates are densely packed with long-glass fibers for a compact block with a high strength-to-weight ratio. Ball bearings, sheave and sideplates UV stabilized with black additive for maximum protection.

Blocks feature Cam-Lock or U-Lock locking systems to lock the shackle in front or side positions, or swivel to keep line from twisting.

The high-load 57 mm Carbo has a broad working range. Use for main and jib sheets on centerboard and keelboats like Lightnings, Dragons, Solings, J/24s and for mainsheet systems on catamarans.

Use for:
- Main/jib sheets
