Why Buy a Sentry Internal Halyard Flagpole?  


Our Sentry Internal Flagpoles are designed to be practical and affordable. They create secure, tamper-proof flag displays for off-site locations and use a system of traditional pulleys and a rope halyard to raise and lower the flag and a cam-action cleat to secure it. The cam-action cleat is only accessible through a lockable panel at the flagpole's base. 


The bronze finish Sentry Internal Halyard Flagpole features an anodized finish for enhanced resistance to corrosion and oxidation. Anodizing bonds the finish to the aluminum surface through an electrical/chemical process to create an attractive, weatherproof flagpole. Satin finish Sentry flagpoles are not anodized from the factory, but a clear anodized Sentry flagpole can be special ordered. For more information, please fill out our contact us form, and one of our Flag Pros will be in touch with you!  


Aluminum doesn't rust like steel but can still show pitting and white deposits from oxidation. An anodized finish can extend your flags' life by preventing stains or snags that come from contact with an oxidized, pitted flagpole surface.

Other Frequently Asked Questions — Sentry Flagpoles 


Do you have any other questions related to our internal halyard flagpoles? Fill out our contact us form today, and a Flag Pro will promptly answer your questions!  


1. How does the internal halyard system work?  


The internal halyard system uses a rope or cable enclosed within the flagpole's structure. You can use this rope to hoist and lower the flag. It is accessed through a lockable door, making it more secure and less susceptible to theft or unauthorized tampering. 


2. Are aluminum internal halyard flagpoles durable?  


Yes, these flagpoles are known for their durability. Aluminum is a lightweight yet strong material that resists rust and corrosion, making it well-suited for outdoor installations. Proper maintenance can further extend the lifespan of these flagpoles. 


3. How do I maintain and clean an aluminum internal halyard flagpole?  


Regular maintenance involves checking the internal halyard system for wear, lubricating moving parts, and inspecting the flagpole's condition. You can use mild soap and water to clean the flagpole's surface. Avoid using abrasive materials that could damage the finish.  


4. Can I fly my flag at half-mast on this flagpole?  


Absolutely, simply open the hatch to access the winch and lower the flag to the halfway mark, then lock the halyard in place and close it back up again. Remember, half-staff days require you to raise the flag to the top and then lower it to half-staff. Check out our resource guide on flag holidays for more information on the days you must fly your flag at half-staff.
