Grease buildup under a commercial sink can turn into plumbing problems and sanitation headaches. The right under-sink grease interceptor has to handle the volume of oily water your kitchen produces while fitting into the space you have. For any warewashing sanitation grease setup, choosing between a heavy plastic interceptor and a compact stainless steel trap affects how much grease you can catch and how easy the unit is to maintain. We put two under-sink grease traps side by side: the Commercial Grease Interceptor Trap 70 lb - Under Sink Grease Trap 10 GPM and the Commercial Grease Interceptor Grease Trap Stainless Under Sink Grease Trap US. Here is a clear breakdown to help you choose.
Quick Verdict: If you want a heavy plastic interceptor with a larger capacity rating and a side-connection installation type, this Beseder model is the stronger choice.

Product Notes
Commercial Grease Interceptor Trap 70 lb - Under Sink Grease Trap 10 GPM
The Beseder grease interceptor is a plastic under-sink unit with overall dimensions of 15.75 x 13.2 x 10.63 inches. Its 1/4-inch thick walls provide a sturdy structure that won't rust, and the reliable seals help keep grease from escaping. The strong latches keep the lid secure during everyday use. This model is the one to pick if you need a heavy-duty plastic interceptor for a sink that sees frequent washing. The catch is that it arrives as a new open-box item with all sales final, so you need to be comfortable with the condition before committing. Also, its blue color and sizeable footprint require a good amount of under-sink clearance, so measure your space carefully.
Commercial Grease Interceptor Grease Trap Stainless Under Sink Grease Trap US
This stainless steel grease trap measures 13.8 x 9.8 x 9 inches and offers a capacity of 18-20L. The package includes a drainage pipe and lid, which gives you the basic components for installation. The compact dimensions make it easy to place under a prep sink or in a tight cabinet. Choose it if you want a smaller footprint and a stainless steel body. The limitation is that the capacity is modest, so it may not be enough for high-volume kitchen drains. The wastewater inlet and outlet are both 4.8 cm, so confirm those sizes match your existing drain setup.
Final Choice by Use Case
The Beseder interceptor is the right fit for a high-output kitchen sink where capacity and a sturdy plastic shell matter most, and where you can accept an open-box unit. The stainless steel grease trap is a better match for a smaller prep sink with lower grease volume, or for a kitchen that wants a simple, compact unit with the drain pipe and lid included.
