[TheForge] Norfolk latch question

[Marc Godbout]

My church has an original Norfolk latch on the main door that they'd
like me to improve. This one's thumb lifter only extends far enough to
lift the bar. People new to the church have a hard time figuring out
how to open this thing as they leave. Now, I suppose having a church
with a one-way door is not the worse thing in the world :-), but we'd
still like to have that hook that I've seen on most other latches.

How far does that hook extend past the door? And how is it normally
operated? Do people lift the hook and pull the door open using the
hook (one-handed operation), or do they lift with the hook and pull
with a handle?

I've also seen bars with lift knobs on them. This is definitely a
two-hand deal. Which is the best way to go?
