EARTHQUAKE & wind RESISTANT TIE-DOWNs
Federal HUD-Approved Earthquake-Resistant Tie-Down & Anchoring Systems
The Xi2 protects your manufactured home from shifting, storms, and seismic movement with an advanced, HUD-approved anchoring system. We install only Xi2 tie-downs, delivering a rigid 4-way hold that won’t loosen or deteriorate like traditional straps—keeping your home safer, more stable, and compliant for years.
Homes that aren’t properly anchored are at high risk during storms, strong winds, or ground movement.
Over time, unanchored or poorly strapped homes can twist, lift, or shift off-center, damaging plumbing, skirting, and support structures.
Outdated strap-style tie-downs secure the home in only two directions and often fail to meet HUD compliance requirements, leaving homeowners vulnerable during severe weather or seismic activity.
Our Solution
Stillwater Leveling installs Xi2 Earthquake-Resistant Bracing Systems, the federally compliant standard for long-term safety and performance. These rigid, galvanized steel systems connect directly to your home’s frame, securing it in all four directions, up, down, and side-to-side. The Xi2’s design eliminates slack and corrosion while providing superior resistance to uplift and lateral movement caused by storms, soil changes, or earthquakes.

Frequently Asked Tie-Down Anchoring Questions
-
Old-style strap systems only secure the home in two directions and can loosen or rust over time. Xi2 anchors provide a 4-way hold, remain rigid, and are made from galvanized steel for long-term strength and compliance.
-
Yes. HUD and FHA require approved anchoring systems like Xi2 for foundation certification and loan eligibility.
-
We recommend releveling first. Anchoring locks the home in its current position, so ensuring it’s level beforehand guarantees a proper, lasting setup.
-
While anchoring greatly minimizes movement, no system can completely prevent shifting. Environmental factors like soil expansion, erosion, or seismic activity can still cause slight changes over time—but not nearly to the extent of an unanchored home.
-
Only if you’re buying, refinancing, or selling your home. The certificate costs $500 and verifies compliance with HUD and lending requirements.
-
Most anchoring projects are completed in one day, depending on access and conditions.
