English: Here a transition strip is being added. Looking down at the space between the kitchen and living room floors. The kitchen floor (bottom) is 3/4 inch higher. So I cut a board at an angle, sanded it, installed it with screws, then the gold plate (middle, above) will cover the sanded board (middle) and serve as a second transition -- between the sanded board and the higher kitchen floor. In addition, I sunk the screw heads in deeper by drilling a wider superficial hole for each screw. That way, the screw head sunk beneath the sanded board, and would not trip anybody walking there.
