Final d, and sometimes final t, or d between vowels, sound very much like L, at least to us non-native speakers. More technically, the final d and t are unreleased and lateralized. The tip of the tongue touches pretty much the same spot for t, d, and L, and if the sides of the tongue are relaxed a bit, it will sound like an L.
Skab is a collective term for any larger-sized pieces of furniture that often have multiple compartments and doors and/or drawers that open to the front side. Fitting English translations are "wardrobe", "cupboard", "cabinet", and maybe "closet", depending on how generous you are with the definition.
