How to Select the Right Manufactured Home Anchor
Selecting the correct anchor for a manufactured home installation is governed by HUD 24 CFR Part 3285 — the Model Manufactured Home Installation Standards. The anchor you choose must be appropriate for the site's wind zone (I, II, or III), soil classification (1 through 4B), and the home's configuration.
The four key variables that determine anchor selection are: installation surface (soil vs. concrete), wind zone (determined by the county per HUD 24 CFR §3280.305), soil class (measured by torque probe or penetrometer per HUD 3285 §12), and home type (single, double, or triple-wide).
Oliver Technologies manufactures anchors for every combination of these variables, from the OT30CDP for solid rock in Wind Zone I to the OT607B 60-inch galvanized anchor for the softest Class 4B soils. All products comply with HUD 3285 installation standards and are manufactured at our facility in Hohenwald, Tennessee since 1995.
For concrete slab installations, wet-set J-shape re-bar anchors (OTCAW-S, OTCAW10-S) are embedded during the concrete pour, while dry-set patio anchors (OTCAD) are used on existing slabs. Wind Zone III installations always require galvanized finish for corrosion resistance in coastal environments.
