Avoid incidents.

Secure your auto-belay lanes.

With the BASS security system.

What BASS does

BASS is a safety device developed by MBS Industry — founded in France by athletes Bassa and Micka Mawem alongside engineer Sébastien Kuehn.

The system connects to every auto-belay at the base of the wall. If a climber starts a route unclipped, it triggers an immediate 110dB audio and visual alarm. Stop. Clip in. Go.

The latest version also detects a second climber entering an occupied lane — a leading cause of serious incidents even among experienced climbers.

Compatible with all auto-belay brands and all wall profiles, no structural modification required.

Climbing gyms don't lack safety protocols. They lack a safety net for human error.

Auto-belays have become standard in almost every gym — they simplify the experience, open up access, and allow solo sessions. But their widespread adoption comes with a cost: accidents related to auto-belays are rising. Not because the equipment fails. Because human distraction is constant.

An experienced climber can start a route without clipping in. One conversation, one phone notification — and the automatic gesture doesn't happen. No training protocol eliminates distraction. It's a systemic problem that requires a systemic solution.
