Flagpole shafts are manufactured in the United States from seamless 6060-T6 aluminum with tensile strength not less than 30,000psi and a yield point of 25,000psi. Shafts in excess of 35′ exposed height are shipped as multiple piece units, then field-assembled with a self aligning internal sleeve assembly (patent pending). All Concord flagpoles are polished to a Deep Luster Finish creating an elegant soft sheen. Other architectural finishes, such as powder coat, clear anodized and Duranodic bronze, are available. In the standard mounting application, Concord flagpoles are produced for the popular ground mount method. In this configuration, the overall shaft length includes the exposed height measurements plus 10% additional that fits into a ground sleeve assembly.
The standard configuration for the Independence Internal Halyard winch system is comprised of a three piece platform with a winch on a patented rotating casting. This allows the winch to be easily positioned for maintenance when needed and then rotated 90 degrees and locked. This allows the handle to enter a hole in the flagpole door.
The SP (Stationary Platform) alternative uses a machined aluminum casting with tamperproof hardware to attach the winch to the rear of the flagpole. The casting is sized for the specific shaft diameter in order to center the winch in the flagpole. In this configuration, the handle enters the flagpole from the side and the winch is positioned in a matter that still provides ease of access for maintenance.
