Auto Shackle Type Ⅲ


The key structure of Auto Shackle Type III enables it to be quickly released. This product has been developed for the purpose of connecting a net and rings at the bottom of the net for purse seine fishing. Quick release and secure rigging capabilities improve work efficiency at work sites. The size M model has a working load limit of 0.8 tons, and the size L model, 1.3 tons. As pioneers in the development of this product, we develop and offer a range of models, such as Type II with an attached rope that releases the gate when it is pulled, and Type IIS, which is an enhanced version of Type II, in order to fulfill work site requirements.

■Material: Special stainless steel

*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. *Spare springs and screws are available (sold separately).  *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.
