Patio Screen Door?

Question:I ordered a patio screen door from Home Depot & can't figure out how to adjust it on the track. The old one had a screw on each side at the bottom & the new does not have this & no instructions. There seems to be screws in side the frame part. One at the bottom & one at the top on each side. How do you adjust these so the screen door will slide properly.

Answers:
Call the home depot and they will explain how to adjust or give you the web address to pull them up
