Product Overview
Our Galvanised Alloy Steel Dee Shackles are manufactured to the highly-regarded U.S. Federal Specification RR-C-271. This standard ensures a high-strength, traceable, and reliable shackle suitable for a wide range of lifting and rigging applications. The 'dee' shape is ideal for in-line connections.
Important Safety Notice: These shackles are load-rated for lifting. The Working Load Limit (W.L.L.) is clearly marked and must not be exceeded. Always inspect shackles for wear, damage, or deformation before each use. For overhead lifting, ensure pins are correctly and securely fastened.
