Harken 416 16mm Cheek Ball Bearing Block
The Harken 416 16mm Cheek Block is a compact, high-performance ball bearing block designed for permanent mounting on flat surfaces where the control line needs to run parallel to the deck, mast or spar. As part of Harken's renowned 16mm Micro Block range, the 416 is engineered for lightweight control systems on dinghies, skiffs, catamarans and performance yachts.
Featuring Harken's patented stainless steel ball bearing system running in a captive grooved race, the Harken 416 delivers exceptionally smooth operation with minimal friction. Its fixed cheek mounting provides a secure, low-profile installation while keeping the control line neatly aligned along the mounting surface.
Designed for modern synthetic control lines up to 5mm diameter, the Harken 416 offers an impressive 113kg maximum working load and 544kg breaking load, making it one of the strongest blocks available in its size class. Whether used for outhauls, cunninghams, traveller controls or leech lines, the Harken 416 provides reliable performance in demanding marine environments.
