2-1/4" is pretty thin for a clutch fan blade.
I've got one of them thats approx. 2-1/4" but the rest are much closer to 3".
The clutch fan blades I've compared are typically a steeper pitch than fixed fan blades.
THE PICH IS 2 1/4'' DEEP - DEEPEST ONE I`VE RAN ACROSS YET ---ALTHO I`VE JUST BEEN NOTICEING THE ONES IN SUMMIT AND JEGS , AND WHATS FOR SALE ON THE INTERNET , MOST ARE 1 3/4'' DEEP PITCH.
