Default NACA vent screen

Has anyone installed a “bug” screen in the air vent? In my RV-10, i installed a small section of window screen over the rear of the aluminum vent. The -14 mounts directly to the NACA duct and I am not seeing a good solution. I am using Steins aluminum vents.
Hoping someone has a nifty solution.

I used regular window screen, over the NACA duct port under the hose. It’s still there after 17 years.

And I use stainless steel screen from a colinder I purchased from the grocery store.

Default Aluminum window screen

I think I "lost" the supplied 3X3 screens in a move.
I found some aluminum window screens, bought the smallest size (24X24 inches) and cut my own.
I installed one on the NACA for the pilot vent.
I forgot to install the second one on the NACA below the wing for the passenger vent.
I put it on the SteinAir passenger vent instead...

I made some out of pvc and screen. Fits in scat tube. Believe there was a kitlanes article on it cause I know I didn’t design it myself

I used nylon window screen on each NACA duct on my RV-8. Learned a lesson on the fuselage screen; should have let the ProSeal set up a bit longer before riveting; it got a little pushed in. The wing one is better.

Two short lengths (~1/4") of PVC pipe with an OD greater than the ID of the vent. Cut lengthwise and remove enough so that the rings will fit into the vent. Install one ring, a circle of stiff screen followed by the second ring. Add about 2 drops of thin CA to each ring... Done..

Same here except just 10 years so far (my screen is nylon).

You can buy small sheets of stainless steel screen mesh from McMaster Carr relatively inexpensively. Just decide what size you need based on bug size, trim to shape with tin snips, then bond in place with sikaflex PU or pro seal. It gives a rigid screen that looks professional, works great and will last the life of the aircraft. The biggest downside is you’ll get a taste for buying parts from McMaster Carr and before you know it half your aircraft is built from McMaster Carr pieces.

Your local Dollar Tree store sells S.S. spatter screens for frying pans @ $1.00 each. That provides enough screening to do a couple planes. I cut mine out and used Pro-Seal to glue them to the edge of the NACA duct connection end after forming the screening edge to fit inside the duct end.
