There is one column unit per pallet and each unit contains 28 two sided corner blocks and one column cap.
It's not recommended drilling the top for a lamp to be added.
We don't have any caps larger than 26"x26". A solution may be to use our 20"x20" caps and modify the sizes to fit. If you have questions or need assistance feel free to call Natural Concrete Products at 888-379-2210. Thank you!

Howdy Ella, You would need to drill holes to run electricity and use a diamond blade with circular saw to cut out stone for mailbox. Any handyman worth his salt should be able to do this. happy building, Coach Dave
They are designed to be stacked on a compacted sub base so a poured foundation is not required. Thank you!
