Joining Section Side Channels

Locate two clearance holes for 1/4-20 hardware on the inside surface of the bottom section side channels (see Figure 11D and Figure 11E). These can be accessed after removal of the bottom wireway cover.

Use two of the four 1-1/4 in. x 1/4-20 hex head thread-forming screws supplied in the hardware kit to join the bottom section side channels. The screw installed at the front is installed from the right-hand section (see Figure 11D).

The screw installed at the rear is installed from the left-hand section (see Figure 11E).

Locate two clearance holes for 1/4-20 hardware on the inside surface of the top section side channels. The front clearance hole is in the left section and is accessible after removal of the top wireway cover (see Figure 11F).

The rear clearance hole is in the right section. In most cases, it will be necessary to remove the section back plate or the top plate to gain access to the rear clearance hole and install the screw (see Figure 11G).
