Grease traps do the dirty work in a commercial kitchen: they catch fats, oils, and grease before sink wastewater flows into the drain line. The right pick depends on your kitchen's output, available cabinet space, and whether you prefer plastic or steel. One under-sink option is a 70 lb plastic unit, while the other is a compact stainless steel trap. Both separate oil from water, but they differ in how they're built and how they fit under a sink.
Quick verdict
If you want a plastic-bodied interceptor with a rugged build, the Beseder 70 lb Plastic Grease Interceptor is the one to consider. If you'd rather have a stainless steel trap that fits into tighter cabinet spaces, the Stainless Steel Under-Sink Grease Trap is the more practical choice for lighter-duty kitchens.

- Stainless Steel Under-Sink Grease Trap: Its compact footprint makes it an easy fit for tighter spaces, and it's designed to handle mineral, animal, vegetable, mixed, and emulsified oils.

Product notes
Beseder 70 lb Plastic Grease Interceptor
If you're leaning toward a plastic-bodied interceptor, the Beseder has a notably thick build: 1/4-inch walls that resist rust and leaks, reliable seals, and powerful latches. The side-connection 2-inch thread simplifies hookup under a sink, and the overall dimensions are workable for a commercial setting. It also sits at the higher end of the price spread, so be ready for a bigger upfront commitment. That's worth factoring into your plan. The catch is the condition-it's described as new open box, so you're getting a unit that has been opened and possibly handled before it reaches you. If that's an acceptable trade-off for a rugged plastic grease interceptor with robust closures, this is your pick.
Stainless Steel Under-Sink Grease Trap
The stainless steel trap is the one to grab when you want a compact unit that arrives in new condition. At 13.8 × 9.8 × 9 inches, it slips into tighter cabinet spaces, and the steel body is designed to separate oil from water across mineral, animal, vegetable, mixed, and emulsified oils. The smooth threaded fitting makes installation direct. What you give up is capacity: the listed 18-20L is smaller than the Beseder's 70 lb rating, so under heavy grease loads you'll need to empty the unit more often. For a smaller kitchen with moderate output, a new steel body and compact footprint make this trap a straightforward choice.
Final choice by use case
The Beseder is the pick when you want a plastic-bodied interceptor; the Stainless Steel Under-Sink Grease Trap is the pick when you want a compact steel-bodied unit. Both do the same basic job, so focus on the trade-offs that matter most for your kitchen.
