    Hello Aframers,

    the locking latch in my vent hood has repeatedly popped up during trip. It occurred several times, finally I had to duct-taped it down. The OEM latch is kinda flimsy and probably vibrated loose during travel. I have not figured out how to add a spring to the latch to force it close. Maybe just add two external hooks and rope it down.

    The hood appears made out of Lexan or some sort of Polycarbonate. Can I drill hole through without shattering it?

    Some of you folks probably had same problem. Can you share your solution?

    Got my own answer. It is definitely not Lexan. I just drill a hole through. Start with a small drill then change to a larger and larger one. The plastic is soft like cheese.

    I plan to put a ball chain down through the ceiling vent. I can lock and unlock from inside.

    I was wandering though Ace Hardware one day and saw this:

    It's called a 'plate display hanger'. I cut it in half (the vertical wires in this photo) to get two sets of two hooks connected by a narrow spring.

    The vent manufacturer provided holes in all the needed places. All I had to do was cut an opening in the screen for the spring.

    When closed, the lower hook goes around the stem of the crank handle:

    It provides just enough tension to keep the vent from working open. And...I still have the other half of the plate holder as a backup.

    I had the same problem with my fantastic fan. I drilled an 3/16 hole hear the front on each side through the cover AND the inside fixed wall. Then I took a metal coat hanger and bent it 90 degrees 1" from the end, then bent 90 degrees again so that it would pass over to the other side. Then I bent it down and back in again so that it went into the hole on the other side.When you're done, the bracket when laid down flat resembles a wide letter U with the 1" long pieces on each side facing in toward each other. The tension on the metal keeps it in place. This has worked well for me on a trip across Canada and back home again and I still use it although i have replaced the coat hanger with a piece of stainless welding rod that won't rust.

    I didn't do a very good job describing what the finished product looks like. The easiest is to say that looks like the symbol for Uber ( the faux cab company) except wider of course to reach across the vent.

    Zephyr - great idea!

    I found and ordered a similar plate hanger from ebay for $4.66.

    Great for peace of mind...
