Is it difficult to put Type B sections together?

There are a number of connecting methods used by gas vent manufacturers. We believe that the AmeriVent® Type B Gas Vent system, manufactured by American Metal Products, is the easiest vent to assemble on the market today. The patented snap-lock locking system allows assembly by just pushing the sections together until you hear a 'click.' There are no male and female openings to line up or locking brackets to worry about-just push and snap the sections together.
