The circumference of the trap is clearly too wide to fit through the hole, but the scene requires that it does. So, how do they get around this? Maybe Tom could squeeze it in. The trap would squash into a narrower shape (as if it were made of a softer material) as it goes through the small gap, then pop into shape once it had reached the other side.
