Series 40 All Purpose Block - Single Cheek
Features:
- Exceptionally high working loads

All purpose (AP) blocks are a great all around solution.

Can be stacked to create a double version, but no more than 60% of the rated working load should be applied to the upper sheave. Stackable with Ronstan Series 40 deck organizers.
