根据门板的宽度和高度确定两轨道固定性的位置并用水平管测水平，再用M8×41㎜的方头螺钉固定。用卷尺测准水平轨与墙壁及两水平轨之间的间距，用水平尺测准水平轨的水平，然后用M6.4×14㎜的小帽螺丝和六角螺帽将水平轨连接件与水平轨和轨道固定性连接固定。用带眼角钢制成两个三角架，然后将其与水平轨的末端用M6.4×14㎜的小帽螺丝、螺帽连接，并用M8×70㎜的膨胀螺栓固定到天棚或墙壁上。
According to the width and height of the door plate, the fixed position of the two rails is determined and the level is measured by the horizontal tube, and then fixed by the square head screw of M8*41. The distance between the horizontal rail and the wall and between the two horizontal rails is measured by tape gauge, and the level of the horizontal rail is measured by level gauge. Then the horizontal rail connectors are fixed by small cap screws and hexagonal nuts of M6.4 *14. Two triangular frames are made of angle steel, and then they are connected with the end of the horizontal rail with M6.4*14_nuts and nuts, and fixed to the ceiling or wall with M8*70_expansion bolts.
