Harken 376 16mm Single Forkhead Ball Bearing Block
The Harken 376 16mm Single Forkhead Block is a compact, high-performance sailing block designed for applications requiring a removable forkhead attachment. Based on Harken's renowned 16mm Micro Block platform, the 376 combines an ultra-lightweight design with exceptional strength, making it ideal for modern dinghies, skiffs, catamarans, trailer yachts and other performance sailing craft.
The forkhead fitting with removable pin allows quick attachment and removal from eye straps or fixed fittings, making it particularly useful where blocks need to be removed for rigging, transport or maintenance. Harken's patented bearing system uses stainless steel ball bearings running in a captive grooved race, delivering exceptionally low friction and smooth operation under load.
Designed for synthetic control lines up to 5mm diameter, the Harken 376 provides a 113kg maximum working load and 544kg breaking load, making it an excellent choice for lightweight sail-control systems where reliability and efficiency are essential.
