The pan sits perpendicular to the frame of the bodygrip trap and actually makes less of an obstruction than vertical wires.
I have used them in my mink boxes and used thin pieces of wood with holes drilled the width of them for the triggers wires to go through. I made a jig for my drill press to make the holes as freehand is a little hard on thin wood(For me anyway).
I actually prefer to bend the triggers in the shape of an "L" just because its easier and works just as good for me. If I don't get the critter going in, I get them when they try and drag the bait out.
