3. CAMP “Atlas” • Lock — screw gate, 40/10/13 kN, 22 mm, 87 g • 2-Lock / 3-Lock — auto-lock, 40/10/13 kN, 22 mm, 92 g
Curious Details
All of these carabiners are D-shaped — no surprise here, since this is the strongest carabiner shape.
The first two are certified to the American rescue standard NFPA 2500 — formerly NFPA 1983 — which requires General Use carabiners, marked “G”, to withstand at least 40/11/11 kN.
All of these options are 1.5–3 times lighter than steel models with comparable strength ratings.
Why would anyone need such “monsters”?
To reduce carabiner weight without sacrificing strength margin.
To keep working loads farther from the carabiner’s ultimate strength — and potentially improve fatigue life under repeated loading.
To extend the life of other aluminum gear — steel tends to chew up softer aluminum alloys much faster.
For bragging rights.
