FREQUENTLY ASKED QUESTIONS (FAQ)
Which line diameter fits the block?
The block has a 16 mm sheave and fits lines up to 6 mm in diameter.
What is the difference between working load and breaking load?
The working load is the load the block is intended to be used with continuously. The breaking load is the load at which the block will fail and should never be used as a design value.
Does the block require maintenance?
The ball bearings generally do not require lubrication. We recommend rinsing the block with fresh water after use in saltwater to prevent salt and dirt from accumulating in the bearings.
