You bet!
Yesterday my partner Doug put a 50 pound weight on top of a SoffitTrap, and then pushed down harder with his hands, and he reports that it still was very solid. He's leaving the weight on over the weekend to see if it sags, but doesn't think it will. (Why would it?) He's also going to put a second 50 pound weight on top of the first one to see what happens, so if you want to come by as a witness let me know.
