•
The correct pipe (to be provided by customer) is as follows:
UTRK-040
Schedule 40 – 3” nominal
•
Heavier steel pipe (sch 80 or sch 120) can be used as long as outer diameter is 3-1/2”.
•
Using the chart provided below, find the
MINIMUM
acceptable pole height above your
finished grade. The suggested pole heights will provide approximately 3' of ground
clearance with the largest module arrays installed. It is strongly recommended that the
pole height meet our minimum specifications.
•
The
MINIMUM
recommended hole depth is 1/3 the total length of the pole – 1/3 in the
ground, 2/3 above the ground.
For example: 10' above grade, 5' below grade – 15' total length.
•
Center pipe in hole, use a level or plumb line to insure pipe is vertical.
•
Fill the hole with concrete (3000 psi minimum strength), and recheck verticality.
•
The pipe may be filled with concrete for added strength (only to approximate ground
level)
•
Allow concrete and pipe to set for a
MINIMUM
of 36 hours before installing Track

Extruded Mounting Rail
Description: The Zomeworks Extruded Rail is
designed to be mounted to structural components
using 3/8” round-head, square-neck bolts. The edges
of the extrusion are different, one side has a slot to
accommodate standard 1/4” hex bolts and the other
5/16” hex bolts (see diagram at right). When
assembling the rack pay attention to this orientation!
