Summary: Flagpoles can be purchased, or use these ideas for your homemade version.These flag pole tips and facts will help assure that your residential flagpole is installed well and will properly support our American flag, even in strong winds.

I wrote the column about flagpoles as a result of the tragic September 11, 2001 terrorist attacks on our country. Within days of the events, I was flooded with emails from people just like you who were flush with renewed patriotism. I think it is wonderful and am so happy that so many people have decided to install a flag pole to fly Old Glory.

Donations

Firefighting happens to be a hobby of mine. The morning of the attack my wife frantically called down to my office and told me to come upstairs and look at the live TV coverage. I knew that firefighters were rushing to the scene and I knew they were going into both buildings to rescue people and try to extinguish the fires. But I also knew something else. I knew both Trade Center Buildings were going to collapse. The structural steel that supports the buildings was severely damaged. Load bearing columns were ripped out by the planes. Other columns had the fireproofing material scraped off. It was just a matter of time before the steel would soften and collapse under the weight of the floors above.

But yet, I knew that firefighters and police officers were climbing the stairs knowing the same thing. They were in a race trying to cool the steel before the collapse would happen. As we know, they lost both races. And we lost hundreds of heroes.

Some Flagpole Facts

The wind exerts a very strong force on flags. Simply hold up a flag on a windy day and you will see what I mean. This means that poles need to be sized for the wind speed and for the size of the flag(s) to be flown on the pole. Tall poles need to be large diameter to offset the pull of the wind. Be sure to match your flag to the size of the pole you buy or make. Most good flag pole manufacturers have sizing charts to help you do this.

In Ground Pole Drainage

If you decide to do a ground-set pole be aware that the sleeve needs to be able to freely drain collected rain and ground water. If it can't do this, then the pole may rust away over time. The danger is that the pole can weaken over time and blow over and hurt you or someone else. You can minimize corrosion by making sure the pole is not surrounded by water. Cut slots in the bottom of any pole sleeve. Set the sleeve on a metal plate and have it welded if possible. This sleeve sits on a poured concrete footer. Before you pour the concrete that holds the sleeve in place, pour three inches of washed gravel on top of the footer. This is done after the sleeve is in place. Any water that goes down around the pole drains into the sleeve, exits the sleeve through the slots and then passes through the gravel to the soil. The concrete is simply poured on top of the gravel and it will not clog the gravel passageways. This drainage is very important. Don't overlook it as you build the foundation for your pole.

Homemade Flagpole Parts

If you are on a tight budget there is no reason why you can't make a pretty nice flagpole on your own. The most challenging parts to get are the truck (flagstaff cap) that sits on top of the pole and the sleeve that is placed in the ground. In reality, only the sleeve may present a problem for you.

Different Truck Designs

The truck I saw that works perfectly for a homemade flagpole was sold at a local flag shop in Cincinnati, OH called Flaggs U.S.A.

At this store, I held in my hand a cast aluminum truck that would fit perfectly over the end of a 2 inch diameter galvanized iron pipe. The cost was about $20.00. If you decide to look at other truck assemblies, you must determine if they fit inside a tube or over the end of the tube. It makes a big difference! The ones that fit inside a pipe or tube must fit very snugly or you will have all sorts of problems. The one that I saw has mounting bolts that you tighten around the outside of the flagpole pipe. Once tight, the truck will not move on top of the pole. The manufacturers listed below also sell truck parts.

The Sleeve

In the column about flagpoles, I tell you to make a sleeve with a steel plate base. This makes it easy to install the sleeve but the plate is not necessary. You simply need a pipe sleeve that has an inner diameter slightly larger than the outer diameter of the flagpole pipe. This pipe can rest on the concrete footer at the bottom of the hole. The challenge is to keep it plumb as you pour the concrete. One method is to tap a slightly oversize square peg into the end of the sleeve. This peg can stick up about a foot or so. Then extend two pieces of wood over the hole in the shape of the letter X that are nailed to the square peg. Drive stakes into the ground and nail the X pieces to the stakes once the sleeve is plumb.

I live close to the water and the water table is less than 2 feet below ground level. My first attempt to mount the pole in concrete resulted in the dirt eroding around the pole/concrete after a rain to where the pole and concrete both could move back and forth. This was after a 6 day wait for the concrete to setup.

Any suggestions would be very much appreciated. My daughter and her Marine Corps husband will be in town soon and I'd like to have the USMC flag flying below Old Glory.

Thanks.

Richard,
You need to install a sleeve or round caisson as you excavate. This pipe is pushed down in the hole as you excavate. It prevents the cave in situation. You then have to pump the hole dry as you pour the concrete. Once the concrete is in the hole, you can stop worrying about the water.

I did use a 12" X 28" cardboard sleeve as I was excavating the hole. This did help as I was getting ready to pour the concrete into the cardboard. I have a PVC sleeve set in the concrete and that holds the pole.

It was AFTER the concrete set and a one week wait that I set the pole into the PVC sleeve that we had our first rain and it was then that the dirt around the 12" cardboard sleeve eroded somewhat allowing the whole setup to move as if it was "floating" in the ground.

Do I need to just go deeper, or should I rig some kind of bracing for the concrete/cardboard sleeve? The pole is 20' high so I need to go at least 2 feet deep.

Thank you very much for your response. I'd very much like to get this resolved. I looked at the concrete today and as it hasn't rained much lately, the concrete is firm. I just don't want it to tip after a good rain.

Richard,
You need to go way deeper......... There should be instructions with the pole. My guess for a 20-foot pole would be a minimum of 4 feet, but that is a guesstimate.

Hi, I just bought my first home, an older home, which came with a inset flagpole out in front. It's a steel two-piece type that the bottom sleeve has two pins to keep the top portion secure. Anyhow, there is no rope, but there is a halyard at the top and a rope tie-off a few feet up from the bottom.

I just bought a new flag with grommets, and I have some white nylon rope, but I'm not real sure how to properly connect the flag and how to string the rope.

Any help would be appreciated.

Thanks, Dean

Dean,
You make a loop with the rope after you have figured a way to get one end through the pulley in the truck at the top of the pole. Visit the websites of the top pole manufacturers for detailed connection details.

We purchased a home a few months ago and there was a 20 ft. sectional pole in the front yard. It just suddenly collapsed to the ground yesterday. Barely no wind. Looked in the ground and there is this 'sleeve' thing (it almost looks like thick cardboard). Only goes about 2 feet into the ground but the steel pole snapped 2" below the ground. There was one 5' x 8' and one 3' x 5' flag on the pole (2 flags). Was it the weight of the flags that took the pole down? (it's been through many windstorms)
Could the pole have just rusted from the inside? (no visible rust)
The pole has always been a little crooked. But now it is lying on the ground.


Thanks, Jenn

One last question: the pole was originally approx. 7 feet from the house. Would it be a good idea to choose another location to install the flagpole? (one where a steel pole won't come through our foyer window?) The pole can be salvaged from what I can see, just would have to get some PVC or that 'sleeve' device.

Thanks again, Jenn

To Homeowner. I have been designing flagpoles for your situation for over 15 years. Recently with a national known flagpole manufacture, Morgan Francis, and now with my own company Flags A
Fly;n.

Your sectional flagpole was not design for flying the quantity and size of flags being flown.

If you are prudent about removing your flags in high winds or ice storms, them you may get away with it. However, do not be surprised if it starts to lean again and then breaks within a few years.

I would suggest moving your flagpole further from your home so that you can fly the flag at half staff without it hitting your home. Any distance less than the overall length of your flagpole will still allow it to hit your home it it falls in that direction.

Love your webpage....
I purchased a home with a a 20 ft pole cemented in my yard, on the edge of a lake. There is no rope on the poll and i'd love to fly a flag. The land is not accessable for a bucket truck. Any suggestions how to get to the top to string it ?
thanks,
carol
