for: The AG Series
A completely different hinge from the AGC hinge, it has no latch to push up. There is a built in "HOOK" right under where the blade drive pokes through that locks the blade on.
To put a blade on your clipper with this hinge, you put the blade on the hinge, turn the clipper on, then just slap it closed. The blade automatically hooks on.
NOTE: Groomers who have a difficult time getting blades on their AGC hinge with the latch, sometimes have this AG hinge installed in its place. It will fit perfectly on any AGC type clipper, and could eliminate your frustrations.
