Frost Protection Strut - Ground Installation
Ground Installation
1. Check the manufacturers set up manual to identify the amount of perimeter blocking required for pier
spacing and roof load. We offer 2 different Joist brackets for use based on amount of load needed.
2. Systems are installed in conjunction with complete Xi2 systems or at separate specified perimeter
support locations.
3. Make sure all organic matter and debris are cleared from pad site.
4. Place U-bolt through pan facing to outside of home and attach lock washers.
5. Press or drive pan into the ground until level and flush with ground surface.
6. Build pier according to State, local, or home manufacturers guidelines.
7. Attach to floor joists approximately 6” in from outside wall using 3/8” X 3” lag bolts in
pre drilled holes in Joist Bracket. Keep strut angle as close to 45 degrees as possible.
8. Install compression strut by placing mount bracket over U-bolt and attach with nuts.
Do not tighten at this time.
9. Insert adjustable T-bar head in top of compression strut with nut screwed to top of the rod
next to T. Slide the T end of strut up and position to rest in the bend of angle iron support.
While holding in place, install a minimum of 4 (#14 X 1” tek screws) self tapping screws into
the holes provided in the compression strut so the two tubes are connected together with a
minimum overlap of 4” to 6”.
10. Tighten nuts on U-bolt at ground pan.
11. Adjust support by tightening T-bar against Joist Bracket support with adjustment nut.
