We are best known for our RIB (Relay in a Box®) brand product lines. We manufacture our products in the heartland of Indiana where every unit is tested before it leaves the production floor to ensure our customers get the product quality they have come to expect. RIB’s ease of installation, product performance and durability are why our customers enjoy confidence and peace of mind in every box with each RIB purchase.
