Though steel grease traps (GT2700 series) and polyethylene grease traps (GT2702 series) are both made by Zurn, they have slightly different sizing. For example, a GT2700-50 has a 4" inlet and outlet while a GT2702-50 has a 3" inlet and outlet. To be sure of the dimensions of your grease trap, check the product detail page for that individual grease trap.
