Our Stainless Steel Interceptors are stronger than poly, just as economical, and guaranteed to last a lifetime.

The Rockford Separators stainless steel interceptors ‘outshine’ their poly competitors at every level. Because they’re stainless steel, they’re inherently stronger, more durable, and more reliable than plastic. And because they’re stainless, they also eliminate the potential for corrosion that exists with conventional steel units. For this reason, we make any of our steel units available in stainless steel! We also offer a Lifetime Warranty on all of our stainless steel units.

Strong & Flexible


Stainless steel construction makes these trench drains less susceptible to the corrosion that can cause drains to hold bacteria. Our trench drains are typically installed flush with the adjoining surface and are delivered ready to install with NO assembly required.

They are available in sizes ranging from 2 feet to 20 feet, but we also offer non-standard lengths. Constructed using 304 stainless steel with 316 stainless steel available upon request.

Industry Leading Designs & Service

With separation as its sole business, Rockford Separators has manufactured quality separation systems for the plumbing industry for over 50 years.

What sets our separators apart from our competition is that our designs follow nature’s law of gravity in separating lighter-than-water waste matter from heavier-than-water waste, retaining both in the separator.

Clogged drain lines are virtually eliminated due to the unique, yet simple design incorporated into Rockford Separators. There is no straight in-and-out travel of waste water from the inlet to the outlet; instead, separator screens and a removable filter screen prevent grease, oil, and other wastes from entering the sewage system.
