Description
The Sentry Series (ISC) provides the security of an internal halyard flagpole with the added strength of a reinforced raised door frame, making it ideal for schools, municipalities, public parks, government buildings, and commercial facilities. This patented design enhances structural rigidity around the access compartment, improving durability in moderate wind speed areas while offering increased tamper resistance.
Built from premium 6063-T6 aluminum, the ISC integrates a secure cam cleat halyard system, a precision revolving truck, and a lockable access compartment—delivering quiet operation, long-lasting performance, and a clean architectural appearance.
