Edelrid HMS Bulletproof Triple ECO – robust HMS biner all purpose

Edelrid HMS Bulletproof Triple ECO – robust HMS biner all purpose

The HMS Bulletproof Screw ECO is an innovative, heavy-duty HMS carabiner built for reliable belaying and long service life. The steel insert at the apex helps prevent premature wear from rope friction or bolt hangers—ideal if you belay often and want your biner to stay smooth over time.

This Edelrid ECO biner line is made more sustainable by skipping anodizing: fewer chemical treatments and less processing, while keeping the same certified strength and safety. You get a clean, natural finish with a lower-impact production footprint.

The H-profile body uses material efficiently to stay as light as possible, while the clean Keylock closure keeps clipping and unclipping smooth. Practical, durable, and designed to pair well with Edelrid belay devices.
