Harken’s Carbo T2™ is the first block with no fasteners, rivets, or other metal parts to add weight. Fiber-reinforced high-strength nylon-resin sideplates have no metal fasteners for the lightest block. Both models route the attachment line through the blockhead and sheave, reducing load on the sideplates and acting as a safety backup for your system. Composite sheave spins on ball bearings with fitted races for low-friction rolling. T2 loop slides through the blockhead and over the anchor post for a secure connection. No knots, splices, or tools required!
The T2 can tie, splice, or lash to almost anything and comes in 29 mm, 40 mm, and 57 mm sizes.
 

• A length of covered Spectra® line is included
• Soft attachments reduce weight and noise while allowing the block to articulate to align with the load
• Requires no lubrication just flush clean with fresh water
