Tie Down Xi2 Foundation System - Manual (Page 3)

Xi2 Longitudinal Stabilization for Wind Zone I, II & III
Single Section
Up to 16’ Nominal
Double Section
Up to 32’ Nominal
Triple Section
up to 48’ Nominal
NOTE: On triple section homes in
WZII & III an additional longitudinal
system is required. It should be
installed on the center section.
When using longitudinal
stabilization only, systems
must be as evenly spaced
as possible, no more than
10’ from the end of the
home. Longitudinal struts
do not replace anchors on
single section homes.
Use One Strut (per end)
For WZ I
Use Two Struts (per end)
For WZ II & III
4 - #12 x 1”
Tek Screws
Installation of Longitudinal Struts
Longitudinal stabilization can be combined economically with the Xi2 Lateral System. Combining LSD struts with the
pad for the lateral system saves time and material costs. When combining the lateral and longitudinal systems, use the
placement directions for the lateral system.
Installation of Longitudinal Struts
1. Identify the number of systems to be used on the
home using the chart below.
2. Clear all organic matter and debris from the
pad site.
3. Place u-bolt though holes provided. Attach lock
washers on u-bolt, on the top side of pad.
4. Press or drive pad into ground until level and flush
with prepared surface.
5. Build pier according to State, local or Home
Manufacturers guidelines.
6. Install frame bracket clamps to I-beam on in
side of block/pier. Do not tighten nuts at this time.
7. Insert u-bolt through mount bracket, attach with
nut and bolt. Do not tighten at this time.
8. Insert strut in the frame bracket clamp, attach
with nut and bolt. Do not tighten at this time.
9. Pull the frame bracket clamp with the fastened strut
outward to remove any slack.
10. Tighten all nuts and bolts on the struts and
beam clamps.
