Help with lower screen door track

by Rachel
(Hamilton, Ontario)

Hello!
I have a french door the goes to my patio and I want to put sliding screen doors on it. Unfortunately I do not know who the manufacture of the door is, and there is no bottom track for installing a sliding screen door. I have found a screen door I want, and it comes with a top track but I do need to find an appropriate bottom track. What would you recommend. The door and bottom are made of wood. I have attached pictures, and included a picture of the screen door I would like to put in, it is from LOWES.

Also, if i were to find a product that would help me, and purchase it from you, in the event it wont work, do you allow returns?

Thank you for your time
