Tools and Supplies You'll Need

You can install Carlton Columns easily using tools found in almost everyone's toolbox. To complete your project you will at least need these basic tools:

  1. 4” x 4” Pressure Treated Wood Post, or 4” x 4” Vinyl PVC, Aluminum, Steel Post
  2. Bagged concrete mix (approximately 2 80# bags per column)
  3. Construction Adhesive/Glue - we recommend either PL® Premium Construction Adhesive, PL® Premium Advanced 8X Construction Adhesive (which has 8x faster bonding), or Great Stuff Pro.
  4. 8” x 10”diameter post hole auger/digger
  5. Concrete mixing container/trowel/access to water
  6. Level/Tape Measure/Utility Knife
  7. Standard Caulking Gun
  8. Hand or Power Saw

Directions:

Prepare 8”-10” diameter hole at desired ground location.

1.) Prepare 8”-10” diameter hole at desired ground location to a depth in conformance with local building codes. (Excavate below frost line as determined by local building code authority, or a minimum of 24”).

Set post into hole and backfill with concrete mix.

2.) Set 4” x 4” post into hole. Prepare concrete mix according to manufacturer’s instructions and backfill hole while making sure post is plumb at all times. Do NOT overfill hole with concrete above existing soil grade surface. Allow post to dry according to concrete mix manufacturer’s recommended cure time. For rapid installation, use a “fast setting” concrete bag mix.

Test fit column base onto post without adhesive.

3.) Test fit by mounting column base (without adhesive) onto post when post concrete is cured. Determine desired mounting height of column. Scribe mark on the post at the top edge of the bracket of the interior mounting channel. Make adjustments if final installation requires raised soil/mulch bed or additional height for desired final grade and column mounting. Remove base unit and squarely saw the post at a 90° angle at scribe mark, eliminating excess post material.

Note: For fencing applications or any 5’ or 6’ height column applications (optional pedestal) using PVC post material, consider filling post with additional concrete for added rigidity and stability. To protect the perimeter of the column from potential damage by lawn mowers or trimmers, it is recommended that a protective mulch bed, gravel bed or landscaping bed be installed.

Mount column base with adhesive, using caulking gun.

3a.) The base should be mounted using the Carlton line adhesive with a caulking gun. Apply 3/8” bead liberally in zigzag direction on all sides of post starting at approximately 10” above grade and progress to the top of the post. Adhesive will start to set in a few hours and will be fully cured in 48 hours.

If you’re not using the Mailbox/newspaper box kit, skip to step 4.

Install newspaper and mailbox inserts using adhesive.

3b.) For Mailbox/Newspaper Box Kit Only

For mailbox kit applications, apply adhesive to bottom of newspaper insert and place into opening. Important: Install newspaper insert prior to installing mailbox. Generously apply adhesive to back of mailbox and insert into mailbox opening. Position mailbox tightly against back wall. Using the Carlton Cobblestone Caulk, seal gap around opening for a finished weather tight seal.

The United States Postal Service Standard recommends the mailbox be set back 6”-8” from the front face of the curb or road edge to the mailbox door (USPS STD-7B02-08-01). We recommend excavating an 8”-10” diameter hole in soil with a centerline measurement of 20” from the face of curb or road edge. Check with your local U.S. Postmaster prior to installation.

Trim the excess material at the top of the bracket.

3c.) For Mailbox Column Applications Only – Top View

Note: It’s important to trim excess mounting post material at top edge of bracket for mailbox applications as this cut surface serves as a mounting pad for the newspaper insert box.

Complete installation by placing cap on top of column using adhesive.

4.) Complete installation by applying Carlton glue on top of column base unit using 3/8” bead. Be careful not to apply bead near outside edge. Place cap in position and apply moderate hand pressure to ensure bonding. Adhesive will start to set in a few hours and will be fully cured in 48 hours.

Excess caulk should be cleaned up.

5.) Attaching Fencing to Column Side a 1” x 6” deck board or pressure treated lumber through bracket. Attach brackets from the outside, screwing through fencing into the column, into the board.

Note: This is for fence attachments only. Gates will require a free standing post next to column.
