The installation methods of the letter box are divided into wall-mounted, embedded, and floor-mounted (standing type)

Wall-mounted type: generally suitable for cabinets with a length and width of less than 1.5 meters. The weight of such cabinets is not too heavy, and the wall can be afforded. When installing, open the letter box on the upper row and load it inside. The edge, that is, the position of the back plate and the flange life, is nailed. The board in this part is relatively thick and has strong bearing capacity. Generally, you only need to hit one on the left and right of the letter box. If the box is too large, it is also in the middle. One is fine. The opening of the letter box is controlled at 1.7 meters above the ground, so that it is easy to pick up the letter.

Embedded: this requires the cooperation of civil engineering, leaving a reserved hole on the wall, which is 1 cm larger than the letter box body, so that it is convenient to embed the letter box. Some manufacturers make embedded letter boxes with closing openings. The back buckle side, so that the appearance is more beautiful, will not leave any gaps, and some do not have back buckle side, then you need to match the size of the opening and the letter box body, and then put glass glue to close the mouth.

Floor type (standing type): This type of letter box is suitable for larger letter boxes. This type of letter box can be placed directly on the ground, but it still needs to be fixed with glass glue or gun nails.
