Tower trees are unique where they have a hollow metal stackable core and branches attached to the metal cone frame.
The metal frame can be bolted together and stacked for taller applications. Electrical connections can be concealed inside the hollow frame for the light wrapped garland branches, which can be easily hung after metal frame is constructed.
Trusted Minleon light sets wrapped on the garland branches. Light sets are a very important component of the tower tree. For example if the lights go bad after one season with some cheaper brand light sets on the trees can become mismatched with newer lights from other brands and other whites.
