T2™ blocks come in single and double configurations and can be tied, spliced, or lashed to almost anything. T2 doubles feature composite line guides that are integrated into the block head. They prevent the block from capsizing by pushing the lashing line to the outer edges of the sideplates.
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.
The 29, 40, and 57 mm 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. Delrin® is a registered trademark of E.
