★ PROFESSIONAL COURSE SERIES · About This Product

Diagonal Red & White Numbered Golf Flags 1-18 (Tube Insert)

Outfitting a full 18-hole golf course requires professional-grade hardware and undeniable visual prestige. The PromoPatriot 14x20 Inch Diagonal Red & White Numbered Flag Set (1-18) delivers classic country club aesthetics with premium groundskeeping durability. Featuring the iconic "semaphore" split-color design, these flags provide maximum contrast against course backgrounds, allowing golfers to easily judge wind direction from the tee box. Crafted from lightweight, wind-catching nylon, they are printed with double-sided numbers 1 through 18 so the hole designation is always legible regardless of wind orientation.

⚠️ Hardware Note: Tube Insert Mount (No Grommets)

Please note that these flags mount using a Rigid Plastic Tube Insert sewn into the hoist. They are designed to slide directly over standard 3/8" or 1/2" professional golf flagsticks and secure with a threaded acorn nut on top. **They do not have grommets**. If you require flags that tie or clip on via brass rings, please view our Grommet golf flag collection!

Care & Maintenance

Keep your 18-hole set looking pristine season after season

Storm Protection

Remove flags from the pins during severe thunderstorms or sustained winds exceeding 40 MPH to protect the tube inserts from cracking under extreme strain.
Washing Off Course Chems

If the nylon fabric becomes stained by mud or liquid course fertilizers, hose them off with fresh water. You may hand wash them in mild detergent to restore brightness.
Air Drying

Because the nylon is naturally waterproof, morning dew will shed easily. If fully washed, leave the flags mounted on the pins in the sun to air dry completely.
Proper Storage

When taking down flags for winterizing the course, ensure they are 100% dry. Store them flat (do not crush the plastic tubes) in a dry locker to prevent mildew.
Acorn Nut Inspection

Periodically check the threaded acorn nuts at the top of your flagsticks. If tightened too much, they can restrict the tube's ability to swivel smoothly in the wind.

Frequently Asked Questions

Everything you need to know about PromoPatriot 14x20" Diagonal Numbered Tube Flags

How do I mount a "Tube Insert" flag to a golf flagstick?

A tube-style golf flag features a rigid plastic cylinder sewn directly into the hoist (the side that attaches to the pole). To mount it, simply unscrew the threaded acorn nut at the top of your professional flagstick, slide the plastic tube completely over the top of the pin, and screw the acorn nut back on to secure it. This mechanism allows the flag to swivel 360 degrees smoothly in the wind without ever wrapping around the pole!

Does this flag have brass grommets for tie-on mounting?

No. This specific 18-hole set features a **Rigid Plastic Tube Insert**. It does not contain brass grommets. If your driving range or practice facility requires flags that mount using zip-ties, string, or swivel clips, please navigate to our "Grommet" golf flag collection!

What does "Dual Numbers" or "Double-Sided" mean?

On cheap, single-sided printed flags, the number will look correct on the front but appear backward (in reverse) on the back. Our "Dual Numbers" flags feature numbers that are printed and oriented correctly on **both sides of the fabric**. This ensures that golfers approaching the green from any angle can clearly read the hole number.

What is a "Semaphore" or Diagonal split design in golf?

A "semaphore" design refers to a flag that is divided diagonally into two contrasting colors (in this case, Red and White). This is a classic, traditional country club aesthetic. The stark diagonal contrast breaks up the visual background of green trees and blue skies, making it much easier for golfers to spot the flag and judge wind direction from hundreds of yards away.

Why is "Lightweight Nylon" used instead of heavy polyester?

In golf, a flag's primary utility is to show the golfer wind direction and speed. If a flag is made of heavy polyester, it hangs dead against the pin and requires a strong gust of wind to move. Our premium **lightweight nylon** is engineered to catch and flutter in the slightest 3-5 MPH morning breezes, giving golfers accurate wind reads while still providing excellent tear-resistance.

Will these tubes fit my existing golf course flagsticks?

Yes. The internal diameter of our plastic tube inserts is designed to universally fit standard professional golf course flagsticks, which are typically **3/8 inch or 1/2 inch in diameter** at the top mounting point.
