Ideal truss has two sides whose braces are all horizontal. That makes two advantages; one is that the workers can easily climb up the truss to install other things such as light or stereo. Another is that we get more choices to place the light. Traditionally, four sides of truss all are 45-degree braces that makes little room for light to place. Unlike the common corner, Ideal Truss has three kinds of corner, 3-sided, 5-sided, and 6-sided corners. The reason is that we seldom use all the 6 side at once. We usually use 3 or 5 side of corner at once. And also, the 3-sided or 5-sided corner are more convenient for the workers to use the tool connect the trusses. Moreover, it can lower the cost of the corner.
