Harken's T2 Soft-Attach Carbo, high-strength, blocks come in 18 to 57 mm sizes. These are the lightest soft-attach blocks Harken has ever designed, because they don't have metal shackles or rivets.
Splice or lash these through their load-bearing center and use for traveler controls, mainsheets, vang cascades, bridles, and other systems where small lightweight blocks are called for.
This 57mm double block features composite sheaves that spin freely on Delrin ball bearings with curved bearing races. A length of Spectra is included.
