40-Foot Aluminum Flagpole with Internal Halyard
Commercial Aluminum
FPA040IH
At 40 feet, the flagpole itself becomes part of the site's identity. A 6x10 flag at this height is visible from a significant distance and makes a statement before anyone reaches the entrance. This is the specification for large government buildings, stadiums, convention centres, and flagship retail locations.

At 40 feet, the flagpole itself becomes part of the site's identity. A 6x10 flag at this height is visible from a significant distance and makes a statement before anyone reaches the entrance. This is the specification for large government buildings, stadiums, convention centres, and flagship retail locations.
The 40-foot uses the same internal halyard system as the rest of the commercial aluminum lineup — locking cam cleat door at the base, 5/16 inch nylon halyard, bronze snap hooks — scaled up for the increased load of a larger flag. The 7-inch butt diameter and 0.188-inch wall thickness give this pole the rigidity its height demands.
Like the 35-foot, this pole uses a fixed shoe base. At 40 feet the fixed base is the right structural choice. Installation requires a more substantial foundation and is best handled by an experienced commercial installer.
Ideal for:
Government buildings, stadiums, convention centres, large-format retail, university campuses, military installations, and any site requiring maximum flag visibility.
Foundation Requirements
Foundation Diameter:
36 inches
Foundation Depth:
56 inches minimum below grade
Concrete Spec:
Anchor Bolts:
3000 PSI minimum
4 x 1 inch dia. x 36 inch galvanized steel, ASTM F1554 GR55
The minimum depth assumes compacted soil. The Building Code typically requires footings below the frost line — generally a minimum of 4 feet (48") below finished grade. Consult your local municipality if in doubt. The anchor cage shipped with the pole is designed for a 4'–6' minimum depth.
Installation Overview
Engineering drawings and full installation instructions ship with the pole. This is a summary for planning purposes.
01
Dig and Pour
Auger or excavate a 26" diameter hole to 44" minimum depth. Bed in gravel, set anchor cage, pour 3,000 PSI concrete. Allow 7 days full cure (or 1 day with quick-set).
03
Walk the pole up
Assemble pole horizontal. Attach hinge pin to base. Two or three people walk the pole up to vertical from the hinge side. Secure the two non-hinge bolts.
02
Level the base
Once cured, thread leveling nuts onto anchor bolts. Place the hinge base plate over the cage, shim level in both directions, and secure with washers and large nuts.
04
Rig and Install
Verify halyard through cam cleat, attach counterweight and snaps, thread the ball finial, install flash collar. Apply silicone bead at collar top. Raise your flag.
