25-Foot Aluminum Flagpole with Internal Halyard
Commercial Aluminum
FPA025IH
The 25-foot aluminum hits the sweet spot for smaller commercial sites. It delivers a professional, permanent installation without the heavier foundation work the taller poles require. At 140 mph unflagged, it carries the highest wind rating in the aluminum lineup — a shorter, stiffer shaft handles wind loads more efficiently.

The 25-foot aluminum hits the sweet spot for smaller commercial sites. It delivers a professional, permanent installation without the heavier foundation work the taller poles require. At 140 mph unflagged, it carries the highest wind rating in the aluminum lineup — a shorter, stiffer shaft handles wind loads more efficiently.
The internal halyard runs entirely inside the shaft, accessible only through a locking aluminum door at the base. No exposed cleat, no rope noise at night, no opportunity for flag theft. The cam cleat and locking door ship with two keys.
The tilt base is standard on the 25-foot, which means one person can lower the pole to horizontal for maintenance with no equipment required. This is the same tilt mechanism used on the 30-foot pole, making these two the most maintenance-friendly options in the commercial aluminum range.
Ideal for:
Smaller commercial lots, residential commercial buildings, franchise locations, schools, churches, Legion halls, and any site where a 30-foot pole would be proportionally too large.
Foundation Requirements
Foundation Diameter:
20 inches
Foundation Depth:
40 inches minimum below grade
Concrete Spec:
Anchor Bolts:
3000 PSI minimum
4 x 3/4 inch dia. x 30 inch galvanized steel
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.
