T2™ Soft-Attach Carbo

Harken® offers these patent-pending, high-strength, soft-attach blocks in 18 to 57 mm sizes. The 18 mm block features stainless steel ball bearings and an integrated stainless inner race and rivet for optimal strength-to-weight. 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.

All T2 blocks are lashed or spliced through the load-bearing center of the block, 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.

T2™ Loop
The T2™ Loop’s on/off loop system slides through the block head and over the anchor post for a secure connection. A SK75 Dyneema® loop is included. Replacement loops available.

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 keep the block aligned correctly by pushing the lashing line to the outer edges of the block's head.

A length of Spectra® line is included.

Customer Reviews

Low-friction Carbo AirBlocks® are lightweight, strong, reliable—and affordable.These are features all sailors look for when choosing sail controls and a real breakthrough in block design. Companions to Harken’s® popular Black Magic® line, these small, compact blocks have very high working loads for safe, easy trimming no matter how hard the wind blows. Sideplates of high-strength engineering resin are UV stabilized to provide excellent protection against long-term exposure to salt water and sun. Carbo blocks are perfect for the small-diameter hard lines favored by racers.
