Outrigger Teaser Pulley - Dual Swivel Teaser Block

Rupp Marine x Harken Dual Swivel Fiddle Block — 29mm & 40mm Purpose-Built Outrigger Teaser & Squid Chain Block

Rupp Marine offers the Harken Dual Swivel Fiddle Block, engineered specifically for outrigger fishing applications. Now available in a new, compact 29mm configuration alongside the 40mm version, this block is ideal for center rigger setups or anglers looking to reduce teaser block footprint without sacrificing performance.

Built around two Harken Carbo Air blocks — available in 29mm or 40mm — this fiddle block delivers the lightweight construction, durability, and reliability Harken is known for. It is purpose-built for pulling large teaser birds or squid chains directly from your outriggers.

Dual swivel posts simplify installation by eliminating the need for a separate rigged swivel, while improved balance keeps the block inline with your rigging under load. A tighter sheave-to-cheek tolerance combined with Harken's proven ball bearing technology extends service life and outperforms previous fiddle block designs.
