An interlocking system, which enables the hook part to be securely locked into the body, has been employed, to generate a high working load.
The shape of the roller edge part covers the body to prevent the purse line from rubbing against it. The roller can be removed and replaced.
If the performance of the spring deteriorates due to certain factors such as aging, the built-in spring can be replaced by removing the screw.
Body, Roller: Special stainless steel
Roller shaft/spring/set screw: SUS304
Bush/lock pin: copper alloy
*Since the roller is made of special stainless steel, so recommended using fiber rope. When using a steel wire rope with this product, there is a possibility the roller will be shaved by wire rope depending on the size of the workload, etc.,
