Cluster Mailbox Installation
- To create a long-lasting, sturdy multiple mailbox stand, buy one length of 2-inch thread galvanized pipe the necessary length for the location. About 4 feet above ground and 2 below means a 6-foot pipe will do. Also buy a galvanized "T" connection and two end caps of a matching diameter. Finally, two lengths of pipe are needed to hold mailboxes on either side of the "T". Allow about 10 inches for each mailbox. Include some bolts or spike nails of at least 6 inches' length. Metal spray paint primer and top coat are optional. All of these materials are standard materials available at any home supply store.
- First, drill holes in the two, short lengths of pipe for each mailbox through each side. Then attach the "T" connector to the long piece of pipe and the two short lengths to each side. Add the end caps to the short pipes at each end. This will keep the pipes from filling with water. Also, drill three holes in the bottom of the long piece of pipe all the way through.
- Dig a post hole at least 18 inches deep and up to 24 inches deep, depending on the soil. Through the holes in the long pipe, insert either long nail spikes or long metal bolts. Mix the concrete, add to the hole and insert the "T" pipe assembly. The bolts in the bottom will act as footings to set the pole and prevent it from twisting inside the concrete. Tie off the post with some line and stake it to keep it vertical until the concrete sets.
After the concrete is dry, fill the remainder of the hole with soil. Using hardware and accessories supplied with the mailboxes, install each to one of the holes in the pipe. - Although the galvanized pipe will hold up well, painting will make it more attractive. Use a good base metal primer and then whatever color desired. Consider painting the entire assembly before installing in the concrete.
