Solera Sliders by Lippert Components provide attractive and economical protection for all of your slide rooms. The Black Solera Slider attaches to both the slide room and the outside wall of the RV, creating a complete seal around the slide room. Dust, smoke, leaves, bugs and debris are blocked by the sleeve even when the slide room is retracted back into the RV. Solera Sliders are designed to fit many different rooms ranging in size from 56" to 188" in length and extend up to 50". Solera Sliders come complete with mounting hardware and awning rail. The hardware hole pattern is universal and will match most competitive brands, alleviating the need to patch holes. To order the correct Solera Slider, select the size that extends a minimum of 2 ½" beyond each side of your slide box width.
