21c gen1 sliding screen door...

[John in Santa Cruz]

My sliding screen door needs some TLC after 10 years....

First, it has a rip near the top of the slide bar

And 2nd, one of the screws holding the track to the floor won't stay down, keeps backing out and blocking the slide thing.

How do you replace the screen and with what type and size of screen? And, what sort of goo should I use to get that screw to stay in?

I'm on the road for 2 more months so nothing is going to happen before I get home
