Auto Shackle Type Ⅳ-A


A new addition to our Auto Shackle Type Ⅳ line-up designed for use with aquaculture nets. A brand-new compact rigging hardware product, Auto Shackle Type IV-A, which inherited the basic concept - "quick release" and "secure rigging" - of ASANO's Auto Shackle series. The gate can be released remotely by pulling a rope attached to the main body. If the performance of the gate spring deteriorates, due to aging or other reasons, it can be replaced with a new one using a hexagonal wrench.

■Material: Special stainless steel, Spring/screw: SUS304

*This product is fishing gear. Do not use it as a hanging hook for cargo handling. *The gate may open unintentionally due to physical shock. *If the gate is released while a load is applied, the main unit may be subjected to strong impact and the product may be damaged, or an accident may occur, such as a released load hitting the surrounding objects or people.
