Single hanging for instance can dow be doubled up, stacking one on top of the other. Thats the beauty of a sliding wardrobe maximising your space, we manufactur them from floor to ceiling, we dont put in traditional kicker boards, sliding wardrobes are fitted to your existing floor. By fitting your new wardrobe to the floor, we can now install a double hanging rail, the first hanging rail goes in at 980mm high approx, your second hanging rail goes in a 1960mm high approx, this means you can reach the highest rail with ease. Also you are left with 300 to 400 mm above this space (depending on your ceiling height). The average ceiling height is about 2440 mm high, you now have a space above your hanging for things like your holiday suitcase, storage boxes, duvets, blankets, pillows, your photo collections that you take down to view once a year.
