One-piece 20 ft residential flagpole with a heavy 4" butt tapering to 2" at the top, made in the USA from 6063-T6 aluminum. Wind-rated to 142 MPH without flag, the 4" butt gives a noticeably stiffer, more commercial feel than the standard 3" pole. Complete kit ships with a gold or silver ball, stationary truck and pulley, 5/16" nylon halyard, vinyl-covered swivel snaps, 9" cleat, and PVC ground sleeve. Available in Satin, Clear Anodized, Bronze Anodized, and Black Anodized finishes.
The 20 ft 4-inch Residential: Built for Open, Windy Lots
The 4-inch butt is engineered for coastal lots, open-plain properties, and anywhere the local design wind speed tops 115 MPH. The larger diameter holds the shaft steady through 30+ MPH gusts and carries a 142 MPH unflagged rating, so it stays true season after season.
Plan on two adults, a weekend, and several bags of high-strength concrete. Dig the 24" × 29" footing, set the included PVC sleeve, pour, cure overnight, and slide the pole in the next morning. Fly a 4×6 ft flag for balance — step up to 5×8 ft only on sheltered inland lots.
Frequently Asked Questions
When is the 4-inch butt the right choice?
Choose the 4-inch when your lot has open exposure on at least one side, you're within 50 miles of a coast, or your jurisdiction's design wind speed exceeds 115 MPH. The heavier butt gives you extra wind margin and a rock-steady shaft in gusty conditions.
Can I install this myself?
Yes. The 20 ft 4-inch weighs ~45 lbs and one adult can lift it into the ground sleeve. The dig, pour, and install fit comfortably into a single weekend.
Will it fit a 5×8 ft flag?
Yes, in inland low-wind areas. For coastal or exposed sites, stick to a 4×6 ft to keep drag load within the pole's envelope.
How Tall Is 20 ft?

This Pole's Specs
Manufacturer-tested wind rating and recommended flag size for this exact model. Sizing your flag correctly keeps the pole within its rated wind speed. See the full sizing guide →
Wind rating reflects manufacturer-tested performance for the flagpole without a flag installed. Flying a flag — especially one larger than recommended — reduces the effective wind rating.
How Installation Works
Our in-ground flagpoles are a one-time install. Most homeowners can DIY in a weekend; we also offer professional installation in Central Ohio.
It Arrives Ready to Install
In-stock flagpoles ship to 48 states. You receive the pole, ground sleeve, hardware, and instructions.
Set the Ground Sleeve
Dig a 18" diameter hole 29" deep, set the included PVC ground sleeve, and pour concrete. Let it cure for 24–48 hours.
Raise Your Flag
Slide the pole directly into the PVC sleeve and seal with 100% Silicone Caulk. Attach your flag with the included rope and snaps, and raise it.
