Boom is a flag pole in the different diameter aluminum tubes which slide into one another. Each section is copied and tightened in place by the upper part (the part that contains the flag). Telescopic shafts has a tangled rope and breakage or the position Clang in the presence of wind. They are produced at the height of 6-35 feet. To bottleneck effect, telescoping pole in general to maintain the force majeure, but not quite as strong as poles of a party.
When looking for a telescopic pole you need to consider three things: the size of the tubes and closures auxiliary spring.
The telescopic pole fort has a diameter greater than its height. If you compare the tree of the same height look larger diameter tubes in each section. The wall thickness, or the thickness of the powders, has to do with a certain force, but not as much as the diameter of the pin.
The closure system varies for different manufacturers, since most manufacturers have issued in the process. Looking for a system that is self-indexing and locking in position. This means that when each part is raised and then automatically guided towards the locking position. The locking system must be positive locking system and not rely on friction or expansion. To minimize the risk of broken locks, try closing system with more moving parts to zero.
Make sure that the manufacturers provide to help the system power supply. In the spring of small flag system of care is a victory for the assembly and employees of which more than twenty feet high spring help is needed because of the heavy pole can range from 12-20 pounds.
