The Door Sill 900MM 1.75M - K is a Kone-compatible elevator door sill designed for use at the lift landing entrance. It serves as the lower guide track where elevator doors slide during opening and closing. This component helps maintain smooth door movement, keeps rollers properly aligned and reduces friction wear on the door system. It is built to fit 900mm wide elevator doors with a 1.75m track length, making it suitable for mid-rise and commercial lifts.
