Barnes & Jones

Barnes & Jones was founded nearly 120 years ago by two engineers, Walter Barnes, a graduate of The Massachusetts Institute of Technology, and Bill Jones a graduate of The Worcester Polytechnic Institute. Around 1897, the two joined forces to design and layout two pipe central steam heating systems for new construction in and around Boston, New York City and Chicago.

Today, Barnes & Jones Inc. manufactures 100% Calibrated Cage Unit inserts for every heating steam trap body ever made. Barnes and Jones products are available throughout North America, Central and South America and most of Europe by over 10,000 representatives. The operating principle, introduced in 1902, remains unchanged as Cage Units emerge, today, as the preferred automatic valving solution for high-tech environmental control systems.
