Common Concerns Answered
Will the 'Element' series from Harken compromise on quality compared to their higher-end blocks?
The Harken Element series is designed to offer robust performance by utilizing specific material choices, such as forged aluminum sideplates and a composite bearing sheave, to maintain structural integrity and longevity while optimizing cost. This 45mm single block is engineered to meet demanding load requirements, ensuring reliability for its intended applications.
Is the swivel on this block as free-moving as more expensive Harken blocks?
While some users may note that the swivel action might not be as exceptionally free as on Harken's premium performance blocks, it is designed to be more than satisfactory for its intended use and price point, providing efficient articulation for rigging adjustments.
Can I use this block for very heavy load applications if I use a smaller diameter line?
This block has a maximum working load of 700kg and is rated for line diameters up to 12mm. While smaller lines can reduce friction, the structural integrity of the block itself is paramount. For loads significantly exceeding its 700kg rating, a block with a larger sheave diameter and higher load rating would be more appropriate.
