Henkjan van der Zouw's Locking Door Latches
Here is one side of a door latch set made by Henkjan van der
Zouw of Holland. These are designed to be very easy to retrofit
to the RV-10 without much effort, as long as you have not filled the
screw heads and painted over your screws on your door latches. He
anodized these, but they could also be polished if desired. They
mount by just removing the 2 screws that hold the latching mechanism
in, and installing the thin plate onto the door. The handle then
attaches, and he included a nice pushbutton that goes in the center
hole that actuates the latch. The more forward hole gets a lock
cylinder that allows you to release a pin that locks into that backing
plate. It should take very little effort to make these work.
If there is a drawback, it's that the plate (about 1/8" thick) is
not flush with the door, so it isn't a flush latch. Some builders
will prefer these for their ease of installation, some will prefer a
flush installation. There is definitely a price difference
though, as it costs much more to design something to replace the whole
interior latch mechanism. These latches will likely sell for
around $200 per PAIR. The other aftermarket latches sold by Coss
Aviation are flush, but they are selling for $350+ *each*.
