Flash, what type of drain setup do you have? Regular, Herbie ... ?
I have done a couple designs on my overflow box and I am going to end up with a plexi cover instead of eggcrate or mesh or etc.
I was going to go with this
But have since decided to make an acrylic cover. It won't be suspended this time; it will sit on top. It'll have tabs on the inside to keep it from sliding around.
The only things that will make it into the overflow will have to get through the teeth.
