Mammut Maillon Anti Twist Lock Swivel - Anodized Aluminum, 23 kN

In climbing and rescue systems, rope twist is more than a nuisance—it's a hazard. The Mammut Maillon Anti Twist Lock eliminates that problem at the source. Unlike standard maillons that allow rotation only when unloaded, this anti-twist swivel integrates sealed ball bearings to provide continuous 360° rotation under load, keeping ropes, slings, and equipment perfectly aligned. The result: smoother belays, cleaner rappels, and fewer tangles in complex rigging.

Highlights

• Anti-twist swivel with sealed ball bearings for 360° rotation under load
• High-strength anodized aluminum body with 23 kN breaking strength
• CE 0333 certified for climbing, rescue, and rigging applications
• Corrosion-resistant anodized finish in black
• Two connection points for versatile integration

In daily use

Whether you're managing a multi-pitch belay, setting up a haul system, or organizing a rescue litter, the Maillon Anti Twist Lock keeps everything turning smoothly. Its compact, robust design adds minimal weight to your rack while delivering maximum reliability. The sealed bearings require no maintenance and perform consistently in dirt, sand, or wet conditions. Connect it between rope and device, or between two slings, and feel the difference immediately—no more fighting the twist.
