What is the recommended pole hole diameter for adequate tamping equipment space?

The recommended pole hole diameter of at least 3 inches all around the pole ensures that there is sufficient space for proper tamping equipment. This extra space is crucial because it allows for adequate access to the pole during installation and helps in the backfilling process. Tamping is important for ensuring that the pole is securely set and stable once it is placed in the hole. If there was insufficient space around the pole, it would be difficult to effectively compact the soil and achieve the necessary stability for the pole. Ensuring at least a 3-inch diameter margin facilitates greater ease of operation and ensures the integrity of the installation process.
