The difference between the low profile latch Bulldog coupler part # BD028499 and the high profile coupler part # BD028463 is the height of the latch and it's design that pulls the collar back.

It's really personal preference between the two. Whichever you would want to use would be the way to go. Only real thing to consider would be clearance. If for some reason you didn't have the clearance for the high profile you would need to go with the low profile.

I attached review videos for these couplers for you to check out as well.
