No need to worry about this when you install a GED Laundry Chute door. All our doors are fitted with a child proof lock as standard. Our most popular laundry chute for the home is 300mm in diameter and the door is at least 1m from floor level. If a child is big/old enough to open our locked door they should be too big to fit in the chute. We care about your families safety. This is why we also have 1 hour UK fire rated doors. Enjoy the practical, time saving, safe and fun way to get your dirty laundry downstairs - safely. USE GED Chutes.
