Help needed - plexiglass inserts for door

I used mirror clips too for the plexi, but on our new MH, I decided to use eisenglass ( clear plastic vinyl used on boat canvas for windows). Unlike the plexiglass, it doesn't rattle and is easy to store by rolling it up. It's held on with Velcro

I just use small tabs with short screws, this has worked great us for years.

I used sticky backed velcro to keep mine in place.

We use mirror clips.

We use mirror clips and small screws to hold the plexi-glass. That way we can easily remove and clean and even leave open during nice days.

Hi--we have had plexglas inserts in all of our motorhomes over the last 25 years. You want to be able to take them out so I don't think silicone is such a great idea. Keeping the in depends on the structure of your screen door. If there is a lip on the door, we have found that door edge guards which are sold for protecting your cars door when contacting something. You slip the protector over the edge while holding the plexi in place. Another solution we find works well is using curtain tension rods which push against the door edges and keeps the plexi from moving. We have used Velcro, double-faced tape, drilled the door and installed turnbuckles, etc. The trick is to be creative and see what works for your installation.
