T2 blocks are available in single and double configurations and can be tied, spliced, or lashed to almost any attachment point. The double blocks feature composite line guides integrated into the block head to prevent capsizing by pushing the lashing line to the outer edges of the sideplates. The 29, 40, and 57 mm models utilize composite sheaves that spin freely on Delrin ball bearings with curved bearing races. Constructed without metal shackles or rivets, these are the lightest soft-attach blocks Harken has ever designed. All T2 blocks route the attachment line through the block head and sheave, decreasing loads on the sideplates and acting as a safety backup for the system.
