This is covered in detail on Product Specifications, as well as the Gate Column General Information and Cost Page. The Columns arrive as 3-sided assemblies that are simply slipped around your post, insuring your wiring is fed out at the bottom before mounting the fourth side to the assembly with the provided screws and plugs in the pre-bored holes. Depending on the post size, the inside of the columns are fitted with spacer blocks to insure a semi-snug fit around 4×4 or 6×6 posts. Pre-bored holes are scheduled for mounting screws through the columns, through the spacer blocks, and into the posts.

Shorter Garden Columns arrive with all four sides permanently assembled. The column is lower over the post that is cut to the prescribed length called out in the drawings.
