Fastening the lining
The cladding with panels should always start from the far corner from the door, since it is the most viewed. Side molding is mounted to the crate, and the first panel is inserted into it and is attached to the frame. All subsequent panels are inserted into the previous. Try to press the lining to exclude cracks at the joints. Back with a hammer, but do not damage the grooves. To do this, you can take an unnecessary piece and use it as a gasket.
