Black Diamond RockLock Screwgate


The RockLock Screwgate features a slightly curved spine to maximise gate opening and a larger rope-bearing surface for greater durability, making it ideal for use with canyoning descenders.

With a snag-free keylock nose, it’s easy to operate with one hand whether abseiling, belaying, or rigging anchors.

The Black Diamond RockLock Screwgate is a HMS carabiner with a smooth round surface that ensures ropes run smoothly with even friction.

The hot forged construction allows extra material to be added at high-wear points, striking a perfect balance between weight, strength, performance, and longevity.

The keylock nose prevents snagging while a slightly curved spine maximises the gate opening.

Note: The Black Diamond RockLock fits the following descenders: Critr, Sqwurel, Element, Pivot, Hoodoo, ATS, Hannibal, No.Mad, Hydrobot and MiniEight. It does not fit the Oka.

Key advantages:

  • Hot forged construction places extra material at high-wear points
  • solid round profile provides smooth friction and longer life
  • snag-free keylock nose
  • easily operated with one hand
