packard shutter thickness

i need a relatively thin shutter for a strange project. I have been looking a t the packard shutters on www.packardshutter.com and they have a suitable size shutter but i can't find out how thick these shutters are. Any help would be great with overall thickness and or distance to the shutter blades from either side. I am interested in the smaller shutters available 3.5 inch square with o 1.5 inch hole. thanks
