Product Description

Harken Industrial 6:1 Diver Recovery Purchase System - 9M Throw

To clean, simply flush pulleys with fresh water. Periodically soaking in fresh water is recommended when used in a marine environment to prevent salt crystal growth. As with all equipment, check regularly to make sure it is in good working order. Check rope for chafe and wear. 

The 443.DRPS can be used for human suspension when a safety factor of 10 is applied and used in conjunction with fall protection.
