We wanted to add a screen door to the side slider so I picked up this screen door from Amazon as the basic materials. For $33 it seemed cheap enough.
It was wider and taller than needed, and I had to make a cutout for my exterior dog door. So I borrowed a sewing machine from my daughter to get started. Of course the first stop was google to figure out how to fill the bobbin and thread the machine and needle. Once that was done I was off to the races. Lots of seam ripping to start with to remove the Velcro on the sides where it’s going to get shortened. Then it was just a matter of figuring out the final sizes and putting the edges back on with the Velcro.
The door attaches to the sidewalls and top frame on the inside of the door. That way the door can still close with the screen in place. The center entry is a magnetic closure so it’s easy to walk through and it re-connects to close up the screen. The bottom was trimmed to float just above the slider track, but below the floor level so it’s not secured in any way there. The door seems to push past it just fine.
The main modification was to allow the exterior access door to still work with the screen up in place. I store dog supplies and my hammock in there along with the outside table lantern.
Seems like it’s going to work out just fine. We will see once we field test it on the next trip to the mountains.
