Hook for Gladiator EZ Connect Shelving Rack

I have both varieties of Gladiator shelves in my garage, and needed to hang some fast mover items. Inexplicably, Gladiator doesn’t seem to sell hooks that mount on the front (or back) of the units. 
 

Enter this hook. It is confirmed to work on both EZ Connect (1 mounting hole) and full size (2 mounting holes) Gladiator shelves. Additionally, the hook can mount on the inside of the shelving unit (see photos) if this is desired. 
 

I labeled files as “left” or “right”. This is based on the EZ connect shelves and is less important for the full size shelves (they have mounting points in both direction on each side of the unit).
