For my application, these cleats have the best thickness (very slim) and tall engagement lip.
I do a thing no other company in my region does. Where OA wins is their extremely low-profile cleat. I have a magic formula to adhere a cleat to glass and OA wins here because it is the lowest-profile cleat I know of. Nobody wants their artwork, or whatever, hanging off the substrate 3/4". OA gets it down to 3/8", which is the best in the game as far as I know. Highly recommend... if you have the secret formula. Hint: "995".
