Long story short, I have an extra screen door opener that I will send to whoever wants it. A few photos are attached that illustrate the installation.
It's really a neat little gadget that eliminates having to open the screen door slider each time someone exits the coach when only using the screen door.
One caveat is the distance between the vertical portion of the screen door slider and the screen door handle needs to be 1-1/2" for the curved metal portion of the device to contact the handle.
Please send me a PM if you would like this gadget. I'll mail it to you postage paid ...
