Learn About TSM


We make irrigation repair easy by developing quality products designed for simple use and installation. We stand behind our products by providing exceptional support for our distributors, contractors and end users.


Solving problems and helping others is our passion. It's what gets us out of bed in the morning, keeps us up at night and has driven us for the last 30 years. When you purchase a TSM product, you can be assured that it was meticulously built with pride and precision as though it was going to be used by our best friend. Each product is built with purpose and crafted with intent to provide you with many years of trouble free service.


We believe in the quality of American made products. All of our business partners as well as the materials that we have produced, are all made in the U.S.A. Any processes that are outsourced are done so with local businesses as well as businesses throughout the U.S. With each purchase you keep Americans employed and provide work to these surrounding communities. We thank you!


Transitional Systems Mfg. was born out of an irrigation service and repair business in 1985. It was originally named The Sprinkler Man by the founder Jim Geiger. While the TSM acronym remained - the mission changed. After years of successfully repairing irrigation systems with a product he developed, it was offered to other irrigation professionals. It was so well received that Jim needed to manufacture it in larger volume. That product was the original Doubler.

Doubler was designed to eliminate the time and expense of fixing broken wires by allowing you to bypass them all together. An all day job could now be done in less than an hour. Doublers' ease of use and durability led to it being used in greater numbers and became the standard in the industry as the solution to broken field wires. No digging or trenching required! Many backs were saved! :)

In 1994, Sean Siebern came on board as an assembly technician and to handle service calls. He soon began working on product design and development as well. As the company and products grew, the TSM name came to be synonymous with solving problems in the irrigation industry. TSM was incorporated in 2001 with Sean acting as VP/COO and by October 2005 he was named as President/CEO.

Over the years we have received many calls from people just like you - many looking for solutions or needing help troubleshooting irrigation systems. We always listen to our customers' needs and your input has even resulted in new products and design updates. As the technologies in the irrigation industry have evolved over time, TSM has updated its products to make use of these new technologies. We continue to invest heavily in R&D to refine and update designs ensuring long service life and equipment compatibility.


We manufacture all of our products in the U.S. and are proud to be putting the "green" in the green industry. We utilize environmentally friendly packaging, our facilities are energy efficient and powered by solar and our manufacturing processes have been optimized to minimize waste.

TSM is always looking for new challenges and problems to solve. We continue to innovate and search for ways to make your job easier. We see many ideas that would benefit from being developed by a company with established distribution channels and reputation for quality.

Through our Collective Technologies division, we work with inventors and other companies to bring new ideas to market. We offer design and development support, manufacturing expertise, distribution, as well as sales and marketing support. To submit your product ideas or to partner with us: click here
