Is this a grease trap or cleanout or what?

What is this thing. It was being used by one sink that did not have a trap. Is it a grease trap?http://i333.photobucket.com/albums/m378/ramdino/IMG_0278.jpg (http://s333.photobucket.com/user/ramdino/media/IMG_0278.jpg.html)

That is an old WADE grease interceptor or grease trap.

That is not a grease trap, it is a Model 5740 solids interceptor. They are normally installed in hair salons to catch the hair. In some cases they are installed as a plaster trap in doctors and dentist offices.

Here is the spec sheet. http://www.wadedrains.com/upload/5740.pdf
