  • 15 lb weight capacity rated to ANSI/ISEA 121-2018
  • Slip-on stainless-steel D-ring fits handles up to 3/4 in
  • Two-pack supplies tether points for multiple hand tools
  • Silver finish on strap and ring resists corrosion

Ergodyne Squids 3790XL Shackle Pair

This two-pack of Ergodyne Squids 3790XL shackles provides secure tethering attachment points for hand tools. Each shackle fits handle diameters from .80 to 1.5 inches and supports a 15 lb weight capacity. They are designed for workers who need reliable drop-prevention connections at height.

Stainless Steel D-Ring and Slip-On Mount

The shackle body and single D-ring are made from stainless steel with a silver finish for corrosion resistance. A slip-on shaft mounting style allows quick installation without tools, while the fixed socket feature keeps the connection stable during use. The 3/4-inch width fits a range of common hand tool handles.

ANSI/ISEA 121-2018 Compliant Tether Upgrade

These shackles meet the ANSI/ISEA 121-2018 standard for dropped-object prevention, replacing improvised loops or worn attachment points. The jump is worth it when a jobsite audit requires certified components or when existing tethers lack a rated shackle connection. They are not suited for tools exceeding the 15 lb limit or handles outside the stated diameter range.
