One Trim Kit has enough trim to cover about 26 linear feet (4 corners can be cut to convert them into straight pieces). Just enough trim to handle a standard 3 car garage with 16 foot and 10 foot garage doors. Norsk finished borders are ONLY compatible with all Norsk interlocking PVC floor tiles. Beveled edges provide an anti-trip feature by creating a transitional ramp effect for the tiled working surface.
