Product Description

OZ-Deck® OD-T4 12″ × 12″ Deck Plate — Load-Bearing Plate for OZ-Post® Anchors

• Load-Bearing Plate Distributes Weight Across the Ground
• Independently Tested — Supports loads exceeding 6,500 lb
• Prevents Posts from Sinking — Spreads bearing pressure and resists settlement
• System Compatible — Designed for use with T4-850 (4×4) and T6-700 (6×6) OZ-Posts
• Saves Time & Effort — No digging or curing vs. traditional concrete footers
• Meets IRC-2006 guidelines for one- and two-family dwellings (verify local code)
• Extends Post Life — Keeps wood out of saturated soil to reduce rot and insect damage
• Performs on Soft Ground — Broad plate footprint helps resist differential movement
• Hot-Dip Galvanized — Heavy zinc coating for long-term corrosion resistance

Build decks, ramps, sheds, and other load-bearing outdoor structures without concrete footers using the OZ-Deck OD-T4. This 12″ × 12″ galvanized plate is driven into the ground together with an OZ-Post anchor, creating a stable footing that has been independently tested to hold 6,500+ lb. The plate is specifically matched to T4-850 (4×4) and T6-700 (6×6, deck-plate use) anchors: simply position each plate, drive the corresponding OZ-Post through the center opening, and fasten your post. In freeze–thaw zones, the broad bearing surface and driven anchor help resist heave and settlement while keeping posts elevated above wet soil.

Why Choose This

• Concrete-free workflow — Set footings and start framing the same day
• Cleaner jobsite — Minimal excavation; ideal where digging is impractical
• Predictable performance — Tested load capacity and system-matched components

Specifications

Installation

Lay out footing locations and call 811 to locate utilities. Place an OD-T4 plate at each mark. Using a manual or jackhammer driver kit, drive the matched OZ-Post anchor through the plate until the sleeve is at grade and the plate bears on the soil. Insert your post and fasten through the sleeve with exterior-grade hardware. In rocky soils, pre-drill or use an alternate footing as required. Follow local building codes for spacing, frost depth requirements, and uplift/bracing details.

Buying Guide

• System pairing: Use OD-T4 plates with T4-850 (4×4) or T6-700 (6×6) anchors for load-bearing applications.
• Quantity: One plate per post/footing location; match to your framing plan.
• Code check: The system has been tested to meet common code requirements, but always confirm local codes for frost depth, lateral bracing, and uplift.

Frequently Asked Questions

Do I still need concrete?

No. When used with the appropriate OZ-Post anchor, the OD-T4 creates a load-bearing footing without concrete.

Which OZ-Post anchors are compatible?

T4-850 (4×4) and T6-700 (6×6 for deck-plate use) are designed to be driven through the center opening of the OD-T4.

What kind of load can it support?

OZ-Deck foundations have been independently tested with loads exceeding 6,500 lb; actual capacity depends on soil conditions and framing.

Is it suitable for freeze–thaw climates?

Yes. The plate’s footprint and driven anchor help resist frost heave and settlement when properly installed.

Will it help posts last longer?

Yes. By elevating wood posts above wet soil and using a galvanized sleeve, the system helps reduce rot and insect damage.
