The security door is counted on several sides

Personally, I suggest that if you can wrap the edge, you should wrap it, after all, the plastering is not reliable.

It depends on what your reference is, because the master who installs the door will generally use the vertical line to adjust the security door of your home to the horizontal and vertical, but because the ground of your home is uneven or the wall itself is crooked, it will cause you to look like the security door is high and low, because you are using the wall or ground as a reference. You can re-hang the perpendicular line to see if it's horizontally or vertically.

The current security doors are all outsourced, and the door has two advantages. 1. Beautiful, consistent inside and outside, coordinated, prevent breaking the wall, and play the role of protecting the corner of the wall; 2. Sealing, the gap between the door frame and the wall is an important part of the sound insulation of the anti-theft door, and the door plays an absolute role in sealing and sound insulation.

The standard size should be 2100*1200, the common single door is 2050*960, 2050*860, and the mother and child door are 2050*1200 >>>More

Generally, it will be agreed in the contract, most of which are calculated according to the external size, and if it is not said to be good, at least the area of one side.
