4. 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 on page 22).
5. 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).
Fasten each section to the floor (see Figure 12) using 1/2 in. or 3/4 in.,
grade 5 or higher, bolts, and flat washers (furnished by customer).
0.88 in. (22 mm) diameter base channel mounting holes provide clearance
for bolt expansion anchors for 1/2 in. bolts.
NOTE: Although sections are free-standing, floor fastening prevents
movement, thereby preventing conduit connection damage.
