Rock Exotica rockSteel Screw-Lock Carabiner


The rockSteel Screw-lock offers impressive strength to weight ratio, a large gate opening and precise handling characteristics due to CNC machined surfaces. Professionals appreciate the smooth spinning screw-sleeve and the smooth keylock surface that won’t snag your rope.

Part Number: M31 SL


The rockSteel offers a surprising strength-to-weight ratio in a carabiner of its capacity. Most steel carabiners are made from 1/2 diameter steel. We use a lighter, 7/16” diameter steel that is heat treated for added strength.

Like our aluminum carabiners, the rockSteel frames are CNC machined for precise fittings and exact tolerances. The result is a carabiner with a high strength-to-weight ratio, keylock snag-resistant nose and a feel like no other steel carabiner in the world.

The rockSteel Screw-lock has been UL tested to NFPA “G” standards.

    • Large frame, with large, 1.2″ gate opening
    • Impressively strong, yet lightweight
    • Rated for inward gate force
    • UL tested to NFPA “G” standards
