The screen is probably in the neighborhood of 10lb. With just the L brackets my frame was a little shaky. I added reinforcement bars and a few T brackets. Stapling the material was actually dead easy. I couldn’t find any felt tape in any brick and mortar store. I’ll probably order Carl’s Black Felt Tape online and cover it up the vinyl tape I used. Light is not leaking any longer. Picture quality is definitely much better than projecting on the wall.
