CM Master Link
Dual Rated For Use With HA800 or HA1000

WLL: 5,400 to 187,800 lbs.
Sizes: 13/32 to 2-3/4 in.

Featuring an optimum design for sling construction, oblong Master Links have a greater capacity when compared with master rings of the same size because of their smaller width. Oblong master links' oval shape is also ideal for use with crane hooks, since the depth of a crane hook is normally greater than the width.

  • Accepts both Herc-Alloy® 800 & 1000 chain and components
  • Durable orange powder coated finish
  • May be used for mechanical and welded sling assemblies
  • 100% proof tested
  • Design factor 4:1
  • Chart Note: Standard sizes dual rated through 1-3/4" only. Special sizes not dual rated.
