Harken 409 16mm Triple Block with Becket Ball Bearing Pulley
The Harken 409 16mm Triple Block with Becket is an ultra-compact, lightweight sailing block designed to create efficient high-purchase control systems on modern dinghies, skiffs, catamarans, sports boats, and other performance sailing craft. As part of Harken's renowned 16mm block range, the 409 combines three low-friction sheaves with an integrated becket, allowing compact tackle systems to be built without adding unnecessary weight or bulk.
The patented Harken bearing system uses stainless steel ball bearings running in a captive grooved race, providing exceptionally smooth operation while securely retaining the bearings during normal use. Designed specifically for small-diameter synthetic control lines up to 5mm, the Harken 409 delivers outstanding efficiency and durability for precision sail controls.
The integrated becket provides a convenient dead-end attachment point, making the block ideal for compact purchase systems including vang, cunningham, outhaul, traveller, and downhaul controls. With its impressive 318kg maximum working load and 544kg breaking load, the Harken 409 offers exceptional performance for its compact size.
Whether you're upgrading a racing dinghy or optimising the running rigging on a high-performance yacht, the Harken 409 delivers the lightweight engineering, smooth operation, and proven reliability expected from genuine Harken hardware.
