The Cobra quick release comes in three sizes; 3/4", 1" and 1.5".
 
Due to the size of the opening of the Cobra clip, if the Cobra clip is used on Super Heavy BioThane, it makes the collar extremely stiff. All collars are made out of Super Heavy BioThane, except for the the following:
 
Quick Release Bungee E-Collar Strap
The Kya Quick Release
