Moving head lifting shackle

with safety bolt and nutscrewstainless steel

Product Overview
Stainless steel shackle manufactured from AISI 316 stainless steel with a 6:1 design factor and highly polished surface finish. Available in Dee (D) and Bow (anchor) configurations, with safety bolt or screw/countersunk pin options. Suitable for marine, offshore, lifting, rigging and corrosion-resistant applications. Working load limit (WLL) from 0.4 t to 10 t.

Introduction
This stainless steel shackle is a corrosion‑resistant rigging component for connecting chains, wire ropes, slings and lifting accessories. Constructed from AISI 316 for enhanced resistance in marine and chemical environments. Dee and Bow variants can be supplied with safety bolt pins for permanent installations or screw/countersunk pins for temporary and frequent assembly applications.
