A locking carabiner provides security and peace of mind for uses where it is critical that
the gate remains closed, such as when belaying, abseiling or at main anchor points. Our
lockers maximise performance, safety and functionality.
We build our locking carabiners to resist worst case scenarios where they are pushed and
levered against edges or loaded heavily when poorly orientated. That means we engineer
our biners to hugely exceed the current EN standards and perform brilliantly out in the
field. They are designed to be functional whilst being as safe and light as possible.
We have the most advanced carabiner hot forging capability in the world and can move
metal around a forging die with expert precision to ensure generous textile-friendly radii,
high strength, and low weight.

Gate Update
THE BALANCE OF GRIP
Optimum
The complete update and improvement to our locking carabiner range for
2017 focuses on the needs of the climber and their interaction with their
equipment. Detailed research, development and design, has combined with
high tech production techniques to create the new generation of locking
carabiners from DMM with the following key benefits:
All of our aluminium lockers are hot forged from high quality 7075-T6 alloy, benefit from a
clean nose design to prevent snagging, and are fully anodised.
For 2017, we have redesigned the gates and locking mechanisms to improve
function, ergonomics, and aesthetics. Extensive research and development
into the ergonomics and functionality of locking gates has been brought
to life using innovative CNC techniques, enabling us to optimise
grip for fast, secure usage in even in the most challenging
conditions.
+ Ease of use in all conditions
+ Sufficient grip in winter gloves
and with sweaty, ‘pumped’ hands
+ Positive and fast handling
+ Snow and ice shedding
› Optimum grip levels for secure,
ergonomic handling
Too Little
›
Hard to operate, especially with icy
gloves or sweaty, chalky hands
Smooth transitions between barrel,
gate, and body to reduce snagging
and encourage safer interaction with
other equipment
