With bugs, snakes and gators, one of the first items purchased for our CYV was this horizontal slider for $850 installed. Also it can be a deterrent for wondering strangers. Unlike the electric vertical sliders, when I'm working outside it's very easy to open and close as you go in and out since each 4' section slides separately. The electric types you'll most likely leave up while cutting the grass, washing the car, etc, which would provide no protection. Plus the fact these are half the price and there's no motor or moving parts to break.
