(Neoprene RV Window Seal and Mounting screws)

This 42” x 12” horizontal teardrop window gives optimum visual appeal . Constructed with a lightweight anodized aluminum frame, our windows are resistant to rust and corrosion. The wide trim with ribbed neoprene gasket adds to the life expectancy by creating a weatherproof seal and offering an eye-appealing finish. The tinted glass will protect the insides of your rig from harsh UV rays but continue to allow the sun to naturally provide light. The window easily slides open to reveal a mesh screen that will conveniently keep bugs out while allowing air to flow through freely. When closed securely, this window will be unable to be pried open from the outside, keeping wildlife and intruders at bay.
