Product Description These inner rubber seals are required only if your Sprinter did not originally come with side windows and you are cutting them in. The seal covers the interior pinch weld and provides a clean, finished edge around the window opening. The seal also sets the correct gap between the glass and the body of the van, which is critical for proper window fitment. If your Sprinter already has fixed factory windows, you can reuse the seals you already have. Pricing is per seal. If you are installing a pair of slider windows, you will need to add both a left and a right seal. (Item #2 in the product image) Note: The right-side seal is shorter to accommodate the slider door.
