This upgrade must be added to a collar with a quick release buckle in the waterproof or fabric/eco canvas collar collections. Available as 1" width. It does not replace the standard tongue buckles on the other types of waterproof collars. Please let me know if you have any questions!
 
The COBRA® locking mechanism is patented and guarantees highest safety. A one-sided opening of the lock is not possible even when under load. Ethos Canine Outfitters only uses authentic COBRA® buckles. The minimum load capacity of the COBRA® is 18 kN (+4000 lbs force).
