PMI Screw Links

Screw links are more capable of supporting multi-directional forces than carabiners while still allowing ample room for a variety of gear attachments. Screw links come in a variety of shapes and sizes in either Stainless Steel (SS), Galvanized (GS), or Aluminum (A) finishes. This product is ideal for harness attachment in ascending systems or for joining anchor straps. NOTE: Links are stamped with a Working Load Limit (WLL) that is about 1/5th of its rated breaking strength.
