NEW to the Karabiner Range!

June 18th 2014


The NEW KL321 Offset Oval Karabiner (with Keylock Nose)


The name 'Offset oval' may sound like a contradiction in terms, but the KL321 combines the specification of an Oval with that of a 'D' shape Karabiner.  True Ovals are not capable of achieving high breaking loads, as their symmetrical shape shares the load between the spine and the gate of the Karabiner.  The weakest part of any Karabiner is the gate and so wherever possible, designers will try to bias the load toward the spine of the Karabiner.  
This is why 'D' shape Karabiners (typically) give the highest breaking loads- our KH219 Iron Wizard (rated at 70kN MBS / 15736lbf) is a good example of this. KH219 Iron Wizard

However, in many industries such as Rope Access & Rope Rescue, the Oval is a popular shape...hence the introduction of our new hybrid KL321 Offset Oval.


Keylock Noses

We have now introduced the process of cold forging, which allows us to offer Keylock style (anti-snag) noses on several Karabiners in our range:

KH311 Oval > for Keylock, use code KL311 (available in Screwgate, Twistlock or Supersafe gate)
