Hello,
As noted in the manual, the width of the RV screen door protector can be adjusted slightly. If needed, please follow these steps:
Loosen the fasteners at the joint of the two panels.
Slide the panels to adjust the width to fit your door frame.
Tighten the fasteners again to lock it in place.
If you have any problems with the adjustment, please contact us with installation photos.
Thank you.
