The Lightpaths ducting system snaps together with a cut-out tool that can be placed over the ducting to allow for vertical drops. All materials are halogen-free. Adapters to interface to existing brands of ducting are also available. Tees, crosses, elbows, drops, and straights come in 8-, 4-, 2-, and 11/4-inch sizes.
