THE ORIGINAL PRESSURE-TYPE WIRE CONNECTOR SINCE 1914
Bill Marr invented the first pressure-type wire connector in 1914, revolutionizing electrical connections. Over 110 years later, Marrette remains synonymous with wire connectors in Canada as part of ABB Installation Products division.
Working as an electrician converting gas lighting to electric in Montreal, Bill Marr, as Scottish immingrant, discovered that connecting wires was tedious and dangerous—requiring buffing, twisting, immersing in molten solder, cooling, and wrapping with tape. Determined to improve safety and efficiency, he created a simple yet ingenious pressure-type connector that made electrical connections faster, safer, and more reliable.
Over 110 years later, Bill Marr's legacy endures. Proudly designed, injection-molded, and assembled in Pointe-Claire, Quebec, Marrette has become synonymous with wire connectors in Canada. What started in a basement workshop has remained the benchmark of excellence in wire connection technology—trusted by professionals and homeowners alike. Marrette is more than a brand—it's part of Canadian electrical history. Today, as part of ABB Installation Products division, Marrette continues its heritage of innovation while maintaining the quality and reliability that made it Canada's most recognized wire connector brand.
CONTINUOUS INNOVATION FOR MODERN ELECTRICAL INSTALLATIONS
Marrette evolved with the industry, introducing the color-coded XTP series for easier size identification and faster installations. The modern PRO-BLU™ 933™ features an ergonomic winged design that improves grip and torque, making installations easier and more efficient. Each innovation builds on Bill Marr's original vision—creating wire connectors that are safer, faster, and more reliable for the professionals who depend on them every day.
Today, Marrette offers complete wire connector solutions: twist-on connectors for traditional applications, lever connectors for quick tool-free installations, push-in connectors for fast terminations, and specialty solutions for unique requirements. The iconic Black Series—including the Marrette 30, 31, 33, and 35—established the standard for reliable wire connections and remains a trusted choice for electricians today. Designed to meet diverse installation needs across residential, commercial, and industrial projects, every Marrette connector delivers the reliable performance professionals demand and the quality Canada has trusted for over a century.
