Aluminum lighting truss comes in different configurations below is a few different types, and my experience with them.

Conical truss

Conical truss is a system of aluminum truss stage that connects to one another without any external accessories. This truss comes with conical and pins, has the best horizontal weight distribution and is very easy to assemble.

Bolt Truss

Bolt lighting truss uses a bolt and nut system to connect between the trusses. This lighting truss system is a little more cost effective. Bolt lighting truss requires tools like ratchets and keys to assemble it takes a little longer as well as many little pieces that can go missing.、
