Household standard doors are generally available in four sizes and are represented by four digits of the width and height of the building opening. For example, when the width of the door hole is 1 meter and the height is 2.1 meters, the specification is called 1021, and the commonly used specifications are 0920, 0921, 1020, 1021, and the like.

Multi-point lock means that in addition to its own lock point, it also drives the sub-lock, forming a plurality of lock points, and distributed around the door frame to enhance the anti-smashing performance.
