18mm Fly Soft-Attach Block

Harken 18mm Fly Soft-Attach Block

The Harken 18mm Fly Soft-Attach Block is engineered to provide strength far beyond what its mass would suggest, giving sport fishermen big power in a low-aero package. Designed specifically for today's small-diameter, extra low-stretch lines or mono, these efficient pulleys deliver an incredible working load for their compact size. They are ideal for dredge retrieval lines and are perfectly suited when mounted to outriggers as the top lead on a dredge halyard system.

At just 7.2 g (0.25 oz), this ultralight block is built around precision stainless steel ball bearings and features an integrated stainless steel inner race and rivet for maximum strength-to-weight performance. The composite fiber-reinforced sideplates further contribute to the block's durability while keeping weight to an absolute minimum.

The soft-attach design allows the block to be tied, spliced, or lashed virtually anywhere on a boat, making it highly versatile across a wide range of sporting and fishing applications. Whether rigged on outriggers, incorporated into a dredge halyard system, or used in other configurations demanding a lightweight but strong running block, the Harken Fly series consistently performs at the highest level.
