Common Concerns Answered
Is the working load limit sufficient for heavy-duty applications?
The 91 kg (200 lb) working load limit is robust for many applications, but for extremely high-tension systems where loads exceed this, alternative high-load blocks may be necessary. This block excels in applications where a balance of control and integrated cleating is prioritized.
Is the cam mechanism difficult to operate?
While the cam mechanism is designed for secure engagement, some users report initial stiffness. This typically eases with use, and proper maintenance ensures smooth operation. The reversible nature offers flexibility regardless of initial stiffness.
Is this block significantly more expensive than basic cam cleats?
The integrated design and Harken's quality construction contribute to its value. While potentially priced higher than standalone, non-pivoting blocks, the convenience of an all-in-one solution and its performance justifies the investment for critical rigging points.
