Ulven #109 Knock Out Pin Shackles – Designed for Controlled Release Under Load

The Ulven #109 Knock Out Pin Shackles are built for high-tension rigging applications, featuring a knock-out pin design that allows safe disconnection while under load. This makes them an ideal choice for professional loggers and yarding crews, where loads must be released without manually unhooking. The knock-out pin requires a sledgehammer or similar tool for release, providing a safer alternative to standard release mechanisms in high-load scenarios. Each shackle comes with a #108 shackle bale and a pin secured with a jam nut and molly hole for enhanced stability. Available in sizes from 3/4" to 2" with Working Load Limits (WLL) from 9 to 52 tons, these shackles offer durability and efficiency for logging, skidding, and pulling applications. While not intended for overhead lifting, they meet industry standards, ensuring reliable and controlled performance in demanding environments.
