Telescoping flagpoles made from aluminum tubes of different diameters slide between each others to make them telescoping. Each flag section can be raised and locked in its place. Telescoping flagpoles are free from ropes and can be used in windy conditions. They can be manufactured in heights of six to thirty five feet. Telescoping flagpoles may be tapered to keep their strength-to height ratios. However, they are still weaker than single-piece flagpoles, check here to know more about the author.
Three things should be considered when selecting a telescoping rod: tubing size, locking systems and spring assistance.
The strongest telescoping flagpoles have the longest diameters. These are also the ones that have the highest height-to-diameter ratio. If you are comparing flagpoles that are the same height, find the longest section. While wall thickness and the thickness of the pole have some correlation to strength, it is not nearly as important as pole diameter.
Each manufacturer will have its own patent which will allow for a wide variety of locking systems. Look for a system which is self-indexing and self locking. Each section automatically locks into its lock position by raising it. The locking system shouldn’t be based on friction or expansion. A lock mechanism that has very few moving parts will reduce the possibility of a poor lock.
It is crucial that the manufacturer includes a spring support system. Spring assist systems allow for smaller flagpoles to be assembled quickly and easily. Spring assistance is required for flagpoles greater than twenty feet high, since the pole weight can be as low as twelve pounds to twenty five pounds.
