DMM UltraO Carabiner

Standard carabiners are used across the world by professionals and novices. The classic oval shape simplifies numerous connections while the round basket permits those connections to self-center when weighted. The Ultra O Carabiners are available as a Screwgate, Kwiklock, Locksafe, or Durolock.

The Ultra O Screwgate Carabiner has a manual locking gate that requires screwing/unscrewing of the barrel to lock/unlock.

Specifications

• Major Axis: 25kN
• Gate Opening: 22mm
• Weight: 67g
• Dimensions: 63mm x 109mm
• Certifications: EN362:2004 B, EN12275:2013 B, UIAA121:2009

The Ultra O Kwiklock and Kwiklock Captive Bar Carabiners have an auto-locking gate that requires two distinct actions to open, which is appropriate when auto-locking gates are needed, rigging arrangements are fairly motionless, and anchor points are simple to monitor.

Specifications

• Major Axis: 25kN
• Gate Opening: 19mm
• Weight: 74g
• Dimensions: 63mm x 109mm
• Certifications: EN362:2004 B/T, EN12275:2013 B, UIAA121:2009

The Ultra O Locksafe, and Locksafe Captive Bar Carabiners have an auto-locking gate that requires three distinct actions to open providing additional safety in complex rigging arrangements, like running ropes or isolated anchor points.

Specifications

• Major Axis: 25kN
• Gate Opening: 19mm
• Weight: 74g
• Dimensions: 63mm x 109mm
• Certifications: EN362:2004 B/T, EN12275:2013 B, UIAA121:2009

The Ultra O Durolock Carabiner has an auto-locking gate that requires four distinct operations to open. Force must be maintained throughout the gate returns to be safe (locked).

Specifications

• Major Axis: 25kN

• Certifications: EN362:2004 B, EN12275:2013 B

Features:

Keylock nose eliminates snagging

This carabiner's nose slots into a groove in the gate, allowing it to achieve full strength without a gate notch. This creates a clean internal profile that won't catch on gear, bolts, or slings, giving easier clipping and removal from systems.

Oval carabiner for rigging stability and central positioning of attachments

Oval carabiners have curved rope baskets for compatibility with slings, ropes, pulleys, and devices. The baskets allow attachments to self-center when loaded, giving greater stability in systems that D-shaped carabiners. Their symmetry allows them to work both ways in rigging systems.

I-Beam construction for optimum strength-to-weight ratio

I-Beam construction techniques allow carabiners to be lighter without compromising strength. This is achieved through hot forging, a process that allows the metal to be made into complex shapes that improve functionality.

Available with a captive bar to secure orientation and prevent tampering

Captive bars ensure carabiners load along their strongest axis by securing their orientation, and can also be used to create tamper-proof systems that cannot be dismantled by users.
