Transitions

Filter By
Bridgeport's extensive line of transition fittings are designed to solve common problems that contractors run into on the job site, like coupling together dissimilar systems. In their broadest application, transition fittings convert two different types of raceways while maintaining the appropriate physical strength and electrical continuity as required by the National Electrical Code. Bridgeport understands what contractors need to safely and quickly transition between systems with un-compromised code compliance. Our expertly designed, agency-listed products allow you to do this faster and easier than ever before.
