Custom Stainless Enclosures, Inc. manufactures custom stainless steel electrical enclosures for all industries. We are the proud manufacturer of 4Xxtreme® Enclosures. We have dedicated our time, knowledge, and effort to developing a revolutionary product that will change the way you view electrical enclosures forever. Our Story Over 12 years ago, while installing electrical enclosures on the kill floor of protein processing facilities, we discovered that existing enclosures couldn't withstand the plant’s harsh washdown environments. All the major electrical enclosure manufacturers were using the same “Foam In-Place” non-replaceable gasket system, which we found when in harsher environments the gaskets would crack, absorb water, and eventually fall off, in less than 6 months. At that point, we decided to develop a better enclosure, creating a solution not just for the protein industry but a new standard of enclosures for all industries facing today’s harshest environments. Our Mission To lower our customers’ overall cost of ownership for their equipment by providing the best electrical enclosures in the industry through quality, innovation, and relentless improvement.
