Product information & specifications

The DMM AmericanO Locksafe Carabiner is a versatile and robust option for climbers, industrial workers, and anyone needing a dependable connection. This carabiner boasts a true oval shape, offering exceptional stability and handling under load.

Built to Last:

Exceeding the American National Standards Institute (ANSI) standards, the AmericanO Locksafe prioritizes safety. Its triple-lock gate ensures accidental opening is virtually impossible, providing peace of mind in critical situations. The carabiner is crafted from high-strength aluminum, making it lightweight (around 94 grams) yet capable of withstanding impressive loads (up to 25kN on the major axis).

Spacious Design:

Larger than the classic DMM Ultra O, the AmericanO Locksafe offers increased space for attaching multiple ropes or webbing slings. This additional capacity makes it ideal for complex rigging systems or connecting various equipment pieces.

ANSI Compliance for Professionals:

The ANSI compliance of the AmericanO Locksafe makes it a great choice for professionals working in industries with strict safety regulations. These could include rope access technicians, arborists, or search and rescue personnel.

Key Features:

  • True oval shape for excellent handling
  • Triple-lock gate for maximum security
  • ANSI/ASSE Z359.12-2019 and CAN/CSA Z259.12-16 certified
