Description
The Harken 57mm Black Magic Low Load Block with Swivel is a top favorite of big boat performance racers and cruisers, built lightweight, free-running, and powerful for sail controls that see constant action: mainsheet, runner, halyard, and spinnaker systems.
A center cage keeps Torlon roller bearings separated and parallel to reduce friction, and the shackle locks in two directions or swivels freely to keep the line from twisting under load. This low-load version uses red isolators alongside Torlon rollers and 316 stainless steel shackles for genuine corrosion resistance.
Rated for a 750kg (1655 lb) maximum working load and 1500kg (3300 lb) breaking load, this block handles a 12mm (7/16 inch) max line diameter at just 154g (5.44 oz). Browse more sailing hardware at CritPro.
Key Features: sheave diameter: 57mm (2-1/4 inch), overall length: 119mm (4-11/16 inch), weight: 154g (5.44 oz), shackle pin: 6mm (1/4 inch), max line diameter: 12mm (7/16 inch), max working load: 750kg (1655 lbs), breaking load: 1500kg (3300 lbs), bearing: Torlon Rollers, shackle material: 316 Stainless Steel.
