I am installing a traditional dry wall hard lit soffit which will transition to an acoustical ceiling the old hard way. These 12-inch stud drops from structure are more likely 3 to 5 foot drops on a real job. That is a lot of time, material and labor wasted. The easy way which I will show you in just a minute is twice as fast. How about eliminating the 11 drops in this demo and replace them with just three hanger wires. For the horizontal run, let's use Armstrong dry wall grid and reduce overall steel framing by about 35%, next hang an HD 8906 main runner at in parallel to the transition point with XL cross tees on 24 inch centers and locking wall angle to eliminate screwing at the wall. Let us screw attach cam utility angle parallel along the length to the face of our HD 8906 main runners. This cam will eventually receive Armstrong transition molding which yes you guessed it is my easy way. I am now installing my horizontal run of dry wall while eliminating all vertical dry wall corner bead, vertical mud, and sanding like in the old hard way. One of eight profiles of Armstrong moldings will now screw attach to the cam utility angle which is attached to my dry wall main runners. There is no need to come back later and install acoustical wall angle because it is integrated into our transition molding along with an integrated tapered mud flange. Do it my way and you will use less material and a whole lot less labor.
