AK Block type PB-S series is developed with assuming use for aquaculture net. Especially the type with a machined nylon sheave perform durability even when it is immersed in seawater.
The main body produces excellent strength with a compact integral structure.
In addition, the material is the special stainless steel with high corrosion resistance often used for industrial parts such as seawater pumps. (excluding machined nylon sheaves.)
Since the rims of the sheave are covered by the main body, a length of rope will not easily become caught between the main body and the sheave.
There is no sharp edges and corners, and the pin/nut is flush the surface, and sunken (they are not sticking outside the surface).
By combining with other metal fittings, the application for use is expanded. Also can be combined with a swivel.
*Material: Special Stainless Steel,
Sheave: MC801 Nylon
