Installation & Foundation Advice

1. Dig & Level: Excavate a 12″ × 12″ hole, 24″ deep. Set our galvanized sleeve perfectly plumb and level.

2. Concrete Fill: Pour at least 300 lb-ft of concrete around the sleeve. Wait 24–48 hours to cure before raising the pole.

3. Erect & Secure:

   • Sectional: Bolt each section using supplied hardware and a torque-rated wrench.

   • Telescoping: Rotate collars to expand each segment; ensure full engagement.

4. Halyard Setup: Thread rope through the truck’s pulley, secure on the cleat, and cycle the line to confirm smooth action.

5. Flag Mounting: Clip on a standard 3′×5′ flag using heavy-duty snap hooks; test raise/lower for clearance and operation.

6. Routine Upkeep: Bi-annual rinse with fresh water, inspect halyards and connectors, and apply silicone spray to the pulley.

FAQs

What flag size is best for a 15 ft pole?
A 3′×5′ nylon flag offers the ideal balance of visibility and sail on a 15 ft pole, ensuring smooth, reliable performance.

Will I need a permit for a 15 ft flagpole?
Many local governments and HOAs permit up to 15 ft without special approval, but always verify your municipality’s codes before installing.

How do I decide between aluminum and fiberglass?
Fiberglass excels in salt-air and high-moisture environments due to corrosion resistance; aluminum provides a sleek, polished look with minimal flex.

Can I adjust the height seasonally?
Absolutely—our telescoping models let you quickly raise or lower the pole for winter storms or special events without disassembly.

How often should I perform maintenance?
Inspect and rinse your pole twice a year, tighten any loose fittings, and lubricate the pulley to keep your flag flying flawlessly.
