If you need to attach the sign to the ground, the best tool for the job is the Cast Iron Pedestal Post Mounting Base. This particular one comes with a 50 inch tall post that has a baked enamel finish to make it look as smooth as possible. This post has holes drilled in to ensure that you can easily mount a standard 12 inch, 18 inch or 24 inch traffic sign, fitting a number of different situations that you could encounter. Also included are all of the nuts and bolts that you would ever need to attach a sign securely. The unit, along with the 14 inch cast iron base, weighs a total of 24 pounds. If you choose the unit with the 17 inch base then it will weigh 40 pounds. Both of these come with several concrete bolts that can be used to secure the base into the pavement. Once this is done it becomes a permanent installation.
