How to use DMM Non Locking Carabiners, Maintenance and Servicing, warnings and lifespan with instructional pictures.
Alpha Trad
Description
The Alpha gives positive handling and easy clipping, with grooves on the spine to provide extra grip. Deep rope baskets help seat gear and ropes, and encourage loading along the Alpha’s strongest axis.
A clean nose helps prevent snagging and accidental gate opening. Superb ergonomics and safe design mean the Alpha excels in any climbing environment.
All-round carabiners can be used across trad, sport, or winter climbing. They are full sized for ease of handling, while I-Beam construction and wire gates keep weight low. If you want one type of carabiner to cover all your climbing needs, you need an all-rounder.
Wire gates are the lightest gate type available, and resist freezing shut in cold conditions. They help reduce rack weight, and are ideal for trad, winter, and alpine climbing.
The gate notch is housed in a recess, creating a smooth inner profile that prevents snagging on gear, ropes and slings. The nose of the carabiner is wider than the gate, helping prevent accidental gate opening caused by rubbing on rock.
The Alpha’s ergonomic spine and grippy grooves give confident handling, and combine with deep rope baskets for easy clipping.
I-Beam construction techniques allow carabiners to be lighter without compromising strength. This is achieved through hot forging, a process which allows metal to be made into complex shapes that improve functionality.
Colored carabiners allow you to color code your rack, making it easier to get the right piece of protection first time on a big trad lead.

The DMM Alpha Trad is a heavily featured and high performing carabiner that is applicable to pretty much any climbing use. They are designed to be ergonomic and easy to use for winter climbing with gloves on, and these same characteristics make them very easy to use for dry rock climbing as well. The only downside is the elevated price tag, but at a minimum, it is worth buying a few for specialty racking needs.
