Common Concerns Answered
Is the locking set screw difficult to access?
While the set screw is accessed through a sheave hole, it is designed for straightforward adjustment with a small tool, ensuring a secure lock once positioned. Users can overcome this by ensuring they have the appropriate small hex key readily available during installation.
Will the Delrin sheave wear out over time?
The Delrin sheave is chosen for its strength and low friction, but like any bearing, lubrication can extend its lifespan. Regular inspection and occasional application of appropriate marine-grade lubricant will mitigate potential wear during extended use.
Is this block worth the higher price compared to simpler options?
The Clear Step Lead Block's specialized design, offering external stanchion routing and superior chafe prevention, justifies its price for sailors prioritizing cockpit organization and line longevity. Its specific functionality for 1" stanchions provides a targeted solution often absent in generic blocks.
