Telescoping Atlantic Flagpole consist of poles made from aluminum tubes with different diameters that slide into each other. Each section is raised to its highest point and locked into place. Telescoping flagpoles are free from ropes that could tangle, wear or bang against the pole in windy weather. They can be made in heights from six to thirty-five foot. Telescoping flagpoles are more durable than one-piece poles due to their tapered effect.
You should consider three factors when searching for a telescoping rod: tubing size and locking systems.
The largest diameters of telescoping flagpoles are those with the highest heights. Compare flagpoles that are the same height by looking for the largest section of tubing. Wall thickness (or thickness of the pole) has some relationship to strength but not as much as pole diameter.
Because most manufacturers have a patent, locking systems can vary between manufacturers. Look for a system which is self-indexing or self-locking. If each section is raised, it will automatically be guided into the locking position. The locking system must not be friction- or expansion-based. You should look for a lock system with minimal to no moving parts in order to minimize the possibility of a broken lock.
A spring assist system should be provided by the manufacturer. For smaller flagpoles, the spring assistance system makes assembly easy. However, for flagpoles with over twenty feet of height, the spring help is required because pole weights can vary between twelve and twenty pounds.
