The belt block comes fastened to the back of the car with two captive screws.
Carefully note the orientation of the block with respect to the car, as shown in
Figure 3-3.

the edges of the section, and note that they are dissimilar. Position the section
so that its orientation matches that of the elevator base.
Figure 3-4 shows a typical Pass-Thru mechanism assembly. The motor drive
section always goes on top, and the base section with the idler pulley always
goes on the bottom. Extension sections are mounted between the motor drive
section and the base section. All sections are joined together with tie bars. For

motor drive and one to the base section. For larger systems, a third support
brace should be mounted near the center of the Pass-Thru mechanism.
