Strawsine sold out long ago, back in the early 90's I tracked down the
manufacturer who still had the molds and had them do a production run for
Clasco. Was funny when they came in with a piece of duct tape as the hinge
on the metal flap. I called them back to complain and the engineer said
that was what the design called for-- he didn't make it....
Guess there was a good reason why they stopped making that vent-- was
pretty cheesey. Today instead of one dinkey latch at the middle of the
flap there is 2 plus 2 tiny plastic pins as hinges that seem to want to
break on first touch! One vent Emery used to make a couple of solenoid
door opening models actually was a pretty good vent, we use one similar but
yea-- those vints are all kinda cheapo.
Putting a screen in there is a good idea-- it's a direct in for many
critters and man don't spray water up at the original vent when you wash
the coach! Most original vents are pretty sad looking today, some people
just block off the thing and forget about the stove vent or just let it
vent into the cabinet like a pile of home stove hoods do.
So I guess to answer your question no-- there is no actual manufacturer
making anything for that vent-- how bout you making one and offer it?
