This screen mod improved the cross flow of fresh air and makes the TT more comfortable.
First things first: Iím well aware this an Emergency Egress Window. I would never recommend anyone modify an emergency exit. That said, it should be obvious I donít believe I compromised our safety or I wouldnít have done it.
The hardware necessary to do this mod was available from a company thatís a window supplier to Jayco. If you decide to do this, you have to find out who made your window Ė they donít all come from the same supplier.
The screen frame pieces join together the same way common residential screen frames do. (One end fits into the other using plastic corner pieces.) The frame also is residential style in that the screen itself is held in a groove with window screen spline. Making the frame was made a whole lot easier by being able to buy the radius corners.
The tricky part is being able to mount the little spring steel clips that secure the window to the frame. In mass production the slots for the clips are pre-punched. When you cut your own lengths from stock, you have to make them. I used a rotary tool and made many real small passes until I had a slot that would hold the clips. I'm sure there are many other ways to hold the screen in place.
Fresh air moving through the camper made it all worth while. (There is only one window on the street side of a 17Z.)
