Do you camp in rainy conditions? These window louvers fit into the window and provide cross ventilation while preventing rain from coming into the trailer. They install in the window track from the outside, and can be easily installed or removed as desired in less than a minute. No drilling or permanent modifications to the trailer are necessary. These come in 14, 16, and 18-inch heights. The 18-inch fit the framed windows on Escapes which have an 18-inch vertical opening. Specifically, these fit the four large side windows on the sides of the 21NE, the large side windows on the 17a, 17b, 19, the two windows near the dinette on the 5.0 and 21C. The 16-inch fit the kitchen window on the 5.0 and the window by the bed in the 21c. The 14-inch is much smaller and fits the optional bathroom window and small windows on the 17, 19, 21NE, and 21C. IMPORTANT: The windows come in left-slide and right-slide models, so make sure to order the correct right or left version of louver to fit. Looking from the outside of the trailer, right haded windows open on the right side, and left handed windows open on the left side.
