We test every single product that leaves our manufacturing floor to ensure quality standards are met, if not exceeded.
Ease of installation and long-lasting quality are what bring RIB customers back again and again. Continued, consistent performance saves time and money, so you don’t have to go back to the jobsite and troubleshoot.
RIB stands the test of time when it comes to quality. We have seen relays on the job installed for over two decades without interruption. The continuous performance and durability give our customers the confidence they need to know when a job is done, it is done well.
The Industry Standard
For over 50 years, HVAC and BAS technicians, electricians, and other contractors have depended on our products to assure their projects go smoothly, on time, and on budget. Trade schools across the country rely on RIB to teach their students how to be productive workers in the field.
Besides being offered at a value price, RIB saves you money every day after install. With long-lasting performance, you won’t have to spend money on truck rolls. Value today & value tomorrow.
