Common Concerns Answered
Is the shackle pin easy to operate with gloves?
While generally easy to use, some users with very thick gloves might find the 4mm (5/32in) shackle pin slightly small. For those requiring superior gloved-hand operation, consider blocks with larger pin diameters.
Can this block handle extremely heavy-duty, continuous loads?
For routine sailing, the 150kg (330lb) working load is robust. However, for extremely heavy-duty, continuous load applications, larger, more substantial blocks might be a more suitable consideration for perceived long-term durability.
How does this block's value compare to heavier-duty options?
The Carbo Air line excels in providing a balance of lightweight strength and low-friction performance at an accessible price point, making it an excellent value for its intended applications. Heavy-duty blocks often carry a higher cost and weight penalty.
