The Oz-Deck™ OD-T4 is an accessory for the T4-850 Oz-Post® to provide load bearing capacity required for deck construction. Oz-Deck™ provides the same strength and stability of conventional construction techniques with less labor and lower cost. Installation is easy; simply locate the Oz-Deck™ plates where your posts are required and drive the Oz-Post® through them. The jackhammer installation method makes installation fast and also compacts the soil beneath the Oz-Deck™ to prevent the Oz-Deck™ from settling over time. The revolutionary design of Oz-Deck™ allows them to be utilized in soft terrain and also in regions that are subjected to freeze/ thaw conditions.
