Perfectly matched to any hatch from the Lewmar range, the window Standard Portlight is stylish, very attractive in terms of cost and very easy to use and also to install. Easiest installation by clamping the deck between the clampring and outer frame. This is done by screwing the fittings into threaded bushings on the frame. The window can be mounted with sealant or closed-pore PVC tape. The inner frame is a white ABS inner frame. The matching cut-out templates can be found in the download at www.lewmar.com.
