Back-clipping is a dangerous lead-climbing error where the rope is clipped through a quickdraw the wrong way, so it runs up against the carabiner’s gate side rather than the spine. In a fall, the rope can press the gate open and unclip itself from the draw. Climbers learn to clip so the rope exits over the front of the carabiner.
Why it’s dangerous
A fall on a back-clipped quickdraw can lever the carabiner gate open and let the rope escape — removing protection mid-fall.
How to avoid it
Clip so the rope runs from the wall side out over the front toward you. Glance at every clip while leading.

Frequently asked questions
What is back-clipping?
It's clipping the rope into a quickdraw so that the climber's end of the rope runs out from behind the carabiner against the gate, instead of from the front. Correctly clipped, the rope runs from the back to the front so it can't lever the gate open.
Why is back-clipping dangerous?
If you fall on a back-clipped draw, the rope can run across and push the carabiner's gate open, allowing the rope to unclip itself — removing that piece of protection at the worst moment. It's a subtle error that can have serious consequences.
How do you avoid back-clipping?
Clip so the rope comes up from the wall side and exits over the front of the carabiner toward you, with the gate facing away from the direction you're climbing. Glance at each clip to confirm the rope runs correctly — a habit worth building from the start.
