I just bought a tub shield from a local glass company. I had it made and it is 3/8" thick, 45" wide and 70" high and weighs approximately 107 pounds. It was made to be installed with 2 hinges. I opened up the box of hinges and the instructions state that with 2 hinges and 3/8" glass that the max weight should be 80 pounds and max width should be 28". Each hinge takes 4 #10 screws. Now i'm worried that the hinges are not going to support the weight of the glass. The hinges will be screwed into the wall through a substrate of 3/8" thick marble tile, 1/2" dry wall and 3.5" depth of wood stud. Am I going to have an issue with this extra weight and width? Does anyone have any glass experience on wide glass panels that can offer any reassurance here? I have attached 3 pics. The first is what the tub shield looks like and the type of hinges that are used. Mine will obviously be wider than what is pictured. The second picture shows the studs. The 3rd picture shows the finished wall. Thanks for any input.
