The master and slave gate is a special double-leaf door to door, from one width smaller door leaf (a door) with a width of larger door (door). Generally the larger door width, to the overall appearance, gate door leaf design into a small form of the master and slave. When you need to design door width greater than ordinary single-door width (800 ~ 1000mm), but there are less than double the total width of the doors (2000 ~ 400mm), you can use the master and slave at the door. This usually open the door to leave, don't push too much of a door; or double door in the small inconvenience of half. When needed, with furniture and other large objects, you can open all. |
