How a Telescoping Flagpole Works

Each section of the pole nests inside the next when collapsed and locks in place with a quarter-turn when extended. To raise the flag you extend each section from the bottom up; to lower for storms, storage, or half staff you simply twist and collapse. No ropes, no pulleys, no halyard tangles.

Installation

Installing this 21 ft telescoping flagpole takes most homeowners under an hour. Dig a hole roughly 24" deep, set the included ABS ground sleeve in concrete, let it cure 24–48 hours, then slide the pole into the sleeve. Full step-by-step instructions are included in the box.

Frequently Asked Questions

How tall is a 21 ft telescoping flagpole when collapsed?

Roughly 6 feet — easy to ship, store, and lower before storms.

Can I fly two flags on this pole?

Yes. The included swivel rings let you fly the US flag on top with a second flag below, both rotating 360°.

How do I put a telescoping flagpole at half staff?

Collapse the top section, raise the flag to the top of the next section, and lock in place. The flag will fly at roughly half the pole's full height.

What flag size works best on a 21 ft pole?

A 3' x 5' nylon flag is standard; a 4' x 6' looks more proportional from the street.

Is it made in the USA?

Yes. Manufactured in America from US-sourced aluminum.
