The Harken 57 mm Aluminium Block with Swivel Becket is a strong, lightweight sailing block designed for smooth, efficient line handling in demanding control systems. Part of Harken’s Black Magic AirBlock range, it combines durable construction with high-load performance and practical rigging versatility.
Free-rolling Torlon roller bearings help reduce friction while delivering an excellent strength-to-weight ratio, allowing the block to perform reliably under significant loads. The 57 mm aluminium sheave provides smooth running and dependable durability for regular use in performance sailing applications.
The swivel fitting allows the block to align with the direction of the load and can also be locked in front or side positions for greater installation flexibility. An integrated becket provides a secure attachment point for the working end of the line, making the block particularly suitable for purchase systems and other mechanical advantage setups.
Designed with straightforward servicing in mind, the block can be dismantled using a single hex wrench. Its compact, refined design makes it a versatile choice for mainsheet systems, control lines and other heavily loaded applications where strength, low friction and reliable operation are essential.
