Reword this in a better way: The ISC Oval Keylock (KL311) combines the specifications 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.

The ISC Oval Accessory Karabiner (3 pack) has a robust 9kN (2023 lbf) Minimum Breaking Strength.
