A key feature of this newly released ring is the proprietary design gate which can be opened with the press of a button. This helps prevent the gate from being opened by accident, ensuring greater safety. The hook uses an interlocking system to securely latch onto the product, allowing for a greater working load limit. Not only can the internal spring in the gate be replaced when experiencing deteriorating performance as a result of aging and other factors, the roller can be replaced as well. This product offers outstanding convenience, and provides the user with peace of mind from not having to worry about durability when using for extended periods of time. SCM roller model for metal wire ropes is also available.
