20-Foot Fiberglass Flagpole with Internal Halyard
Fiberglass

The 20-foot fiberglass carries the highest wind rating of any pole in the lineup at 210 mph unflagged. A shorter, stiffer shaft handles wind load exceptionally well, making this the right choice for exposed coastal sites, rooftop installations, or anywhere weather is a primary concern.

The 20-foot fiberglass carries the highest wind rating of any pole in the lineup at 210 mph unflagged. A shorter, stiffer shaft handles wind load exceptionally well, making this the right choice for exposed coastal sites, rooftop installations, or anywhere weather is a primary concern.
The white gelcoat finish is permanently moulded into the fiberglass itself — it will not flake, oxidize, or need repainting. The pole is manufactured through a hot-moulding process that makes it both lightweight and flexible. Unlike aluminum, fiberglass flexes in extreme wind rather than denting or creasing, then returns to plumb.
Fiberglass is non-conductive, which means it will not attract lightning and does not require a grounding rod at the base. For any installation where running a grounding system is difficult, costly, or where grounding regulations are unclear, this is a significant practical advantage over aluminum.
Ideal for:
Coastal sites, exposed locations, rooftop installations, marinas, properties where grounding is impractical, and any buyer who wants zero exterior maintenance.
Foundation Requirements
Foundation Diameter:
30 inches
Foundation Depth:
30 inches minimum below grade
Concrete Spec:
Anchor Bolts:
300 kg minimum
M16 threaded anchor rods (included)
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.
