Don't know about the Skycatch, but the male part of the Hatchlatch is a teflon or nylon knob that they tell you to epoxy onto the stock Cessna door stop which is attached to either the wing (A&B models) or the wing strut (48 model). I didn't trust epoxy alone so I pinned it in place using a piece of safety wire in addition to the epoxy. No,I don't have any basis of approval for that mod, sorry.
I really like the Hatchlatch set-up, the only trouble I've ever had with it was when I let the door get away from me when opening it with a strong tailwind. The door skewered itself on the striker, and I had a hell of a time un-skewering it. My own fault, not the Hatchlatch's.
The original installation instructions/kit included a small roll-pin to help attach the nylon striker. The nylon would break when an unknowledgeable/careless passenger place any weight at all on the door entering/exiting the aircraft. The new strikers from Johnny Williams are made from stainless and should be much more durable.

Yes the striker is nice!
But he doesn't have the Hatch Latch part that goes on the door anymore.
Thus you get a Tinnerman nut to install with your very nice striker, which isn't working for me.
