Rock Exotica Assault Stainless Steel Screw-Lock


The Assault Stainless provides the versatility of a pear-shape or HMS style carabiner, with the added durability and service life found in a stainless steel connector. The wide top area of the carabiner easily accommodates a large range of gear, webbing or ropes, for the broadest range of uses for this connector.

Not only is the frame made from stainless steel, but also the components within the carabiner. Each piece will resist corrosion far beyond the equivalent materials found in other non-stainless carabiners.


The Assault Stainless features several unique Rock Exotica design elements: snag-resistant keylock nose design, lock-status indicator, precision machined frame, and an angled gate for maximum gate opening.

    • Wide top radius allows the connection of multiple items
    • Precision machined parts for smooth & ergonomic operation
    • All stainless-steel parts
  • Rock Exotica carabiner design elements: keylock nose, lock-status indicator, machined frame, and angled gate.


Spin gate downward and open. 2-stage mechanism.
