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 side plates.

The 18 mm block features stainless steel ball bearings and an integrated stainless inner race and rivet for optimal strength-to-weight.

All T2 blocks route the attachment line through the block head and sheave, decreasing the loads on the side plates 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.
