NSI Industries

NSI Industries is a market-leading provider of branded electrical products sold through a network of third-party distributors and supported by strong manufacturing capabilities. The company’s iconic brands—among them, Bridgeport, Polaris, and Tork—are coveted by contractors for superior durability, reliability, and functionality. Products include insulated connectors, fittings, wire management products, and other high-value-add components with replenishment-driven demand. NSI has delivered impressive and consistent sales growth across its electrical platform.

With Sentinel’s support, NSI transformed into a focused, pure-play electrical products platform shortly after closing by divesting its HVAC division. Half a year later, after unlocking considerable value through this repositioning, NSI was sold to Hubbell Incorporated (NYSE: HUBB) for $3.0 billion.
