Assembly Steps
To ensure an accurate assembly of the MATT™ Terminal, it is recommended that steps be
completed in order. ALL STEPS MUST BE COMPLETED.
Below ground portions in some assembly steps are not shown for clarity.
See Step 16 for bolt/nuts combinations that must be torqued to 65 ft-lb [88 Nm] (+/- 3 ft-lb)
[+/- 4 Nm].
After the system is fully assembled, for Steps 5A and 5B, tighten the double/single
spacers to a snug position with a minimum of two (2) bolt threads protruding beyond the
nut for all hardware that was assembled loosely, ensuring bolt is seated for these steps.
