Gate Styles
We produce six different types of gate locking mechanisms which are available on both steel and aluminium carabiners. We use 7075 T6 alloy for our aluminium carabiners, this gives us optimum push-in strengths.

Screwgate
This, the original and classic double-action gate mechanism, is suitable for a multitude of attachment situations. DMM screwgate barrels feature a new screw knurled profile to assist gripping in wet or icy conditions. We have recently increased the thickness of the gate and thimble. This will increase the thimble/latch overlap, giving greater security. In addition, and most importantly, it increases the minor axis (cross gate) strength significantly.
Kwiklock
The Kwiklock automatic locking system is the fastest gate locking mechanism to operate. It also provides a convenient solution to eliminating the chance that the gate will accidentally be left unlocked. DMM Kwiklock barrels are available in aluminium and steel.
Locksafe
The triple action of the innovative Locksafe mechanism significantly reduces the chance of accidental gate opening and is a major step forward in improving the safety of automatic locking carabiners. Available on all DMM locking carabiners.
Steel ANSI Z359.1(07)
These high strength steel mechanisms are available in both Kwiklock & Locksafe on all steel carabiner styles. We guarantee a minimum strength of 16kN(3600lbs) when tested and loaded in accordance to the ANSI Z359.1(07) standard during push-in and side loading of the gate mechanism.
Aluminium ANSI Z359.1(07)
These DMM patented high strength aluminium mechanisms are available in both Kwiklock & Locksafe on numerous DMM carabiner styles. We guarantee a minimum strength of 16kN(3600lbs) when tested and loaded in accordance to the ANSI Z359.1(07) standard during push-in and side loading of the gate mechanism. Ergonomically shaped, the barrel has been designed for easy operation, with minimal weight increase compared to standard gate mechanisms.
