C4-850

Oz-Post model C4-850 is designed for 4x4 “rough cut” wood posts. This post is ideal for fencing and sign posts and is one of the most popular Oz-Post models. The C4-850 is designed for standard fencing that is 6’-7’ high with post spacing of 8’. For 8’ tall fencing the post spacing should be 6’ which is standard practice for alternative post installation methods. One thing to keep in mind is that throughout the country many areas name post sizes in different ways. So to avoid confusion Oz-Post uses actual sizes and not nominal sizes in our specifications. For example you may order a “4x4” at your lumber yard but the actual size may be 3 ½” or 3 Ύ” or even full 4” square. For this reason we recommend measuring the posts that you are intending to use and matching the size to the corresponding Oz-Post support. For “standard” 4x4’s which are 3 ½” square you will order the T4-600 or T4-850. For rough cut 4x4’s which are about 3 Ύ” square you will order this model and for full cut 4x4’s you will need P4-850. This model includes 8 galvanized screws to attach the wood post to the Oz-Post. When installed as recommended the connection will provide you and/or your customers with a strong foundation for your construction project. There are several options for installing this post, these options are explained in the how-to instructions of this site. To summarize, you can leave the top sleeve completely above ground, half in half out (recommended) or completely bury the top sleeve out of sight. Regardless of what you plan to build with Oz-Post you can be sure that your post will be sturdy. The Oz-Post will also help prevent your post from premature rot that can occur with direct burial of wooden posts. INSTALLATION: Option 1 – Jackhammer: use the Oz-Hammer model OH-01 and Hammer-Spacer model HSP-T4. Jackhammers are easy to operate and available to rent at all rental centers in the country. Oz-Post recommends an electric or gas powered jackhammer. Pneumatic jackhammers are also ok but they are often much heavier and unnecessary. Option 2 – Sledgehammer: cut scrap piece of wood about 8” and insert into the top sleeve. Strike the wood with the head of the hammer to drive the post into the ground. HINT: Be sure that the scrap piece is a loose fit so that it is not difficult to remove after the post is installed.
