The Profraft 5/8″ 3.25T Screw Pin shackles are a good, affordable, all around slackline shackle. The screw pin is the most common type of shackle due to its ease of use but does have some disadvantages to the bolt style shackle. Load Rated Screw Pin Anchor (SPA) Shackles are hot dipped galvanized and meet or exceeds US Fed Spec RRC-271 Type IVA Class 2 Grade A. Screw pin shackles can be used for static line lock off, connections to pullies, rigging plates and are big enough to fit the largest of anchor points.
DO NOT use screw pin shackles or fit pins in contact with moving parts if the pin can roll and unscrew.
WARNING – Be careful when using the screw pin shackles for a line locker. While screwing the pin, there is a risk that the webbing may become caught in the threads, potentially damaging the webbing.
