The blocks feature composite sheaves that spin freely on Delrin® ball bearings with curved bearing races. They have no metal shackles or rivets, making them the lightest soft-attach blocks Harken has ever designed. 

All T2 blocks route the attachment line through the block head and sheave, decreasing the loads on the sideplates and acting as a safety backup for the system. Use for traveler controls, mainsheets and vangs, cascades, bridles, and other systems where small lightweight blocks are called for. 

A length of Spectra® line is included.

Sheave Ø 57 mm

Maximum line Ø 11 mm
