Product Description

Harken 18 mm Fly Soft Attach Block — Narrow

T2 blocks come in single and double configurations and can be tied, spliced, or lashed to almost anything. 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 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 the 2161 “tight cinching” 18 mm in applications where the block needs to be secured extremely close to the deck.

A length of Spectra® line with a polyester cover is included.
