Tolco Corporation was founded by William E. Spengler in March 1961. We began with just one product, the D-22 drum pump, which we still sell today. It was that best in class product which would be the foundation of our success. In the years that followed, we began developing the products that would define their categories. The D-22 was just the start, followed by the Model 320 trigger sprayer, the 942 pump-up sprayer, and continuing today with innovative, category leading products like Komodo Urinal Mats and Top Performer. We are committed to provide you with exciting, innovative products well into the future.
