When the Helium concept was initially launched a major focus was to make a wire gate but with none of the traditional drawbacks a wire has; that they can hook up on bolts or wires, can unclip more easily than snap gates, and are susceptible to opening if lying against the rock.
To get round these took a lot of 'blue sky' thinking, a lot of pencils and a shedload of engineering time. The solution was the 'Clean-wire' hooded nose and the new flat-wire gate. With this combination of features the Helium counters to a huge degree all these traditional problems by covering the gate within the nose not allowing it to get hooked up. Other Helium features that have contributed to its success are the fact it has a Hot Forged I Beam Back which gives it amazing strength for its weight, 10kN gate open for example. It is also a full size biner which all other biners of this weight aren't so it fits in the hand well and is easy to use. It has also been designed to place the rope in exactly the right place to maximise strength at all times and the slight 'pip' at each end helps the rope to sit correctly and load correctly.
Reviews for the Helium have been superb all around the world recognising it's brilliant engineering and the contribution it make to lightening the climber's load - and as we all know the less weight we have to drag behind us the further we'll get.
“The Helium Clean Wire is the first carabiner to use the "I-beam" construction that makes steel girders strong yet light. This application gives the Helium the best strength-to-weight ratio of any carabiner. At a scant 1.2 ounces, it's the lightest full-size biner ever made. With strengths of 24 kN major axis, 7 kN minor axis and 10 kN with its gate open, it is one of the strongest biners out there.” Quote from Duane Raleigh Editor Rock and Ice Magazine USA 2005.
