Wintriss Controls Group Acquires ISB
Wintriss Controls Group LLC has announced that as of October 1st, 2025, it has acquired all of the assets of ISB, a manufacturer of safety equipment for the metal forming industry based in Montreal, QC, Canada. This Wintriss ISB acquisition includes the formation of a new Canadian company named Wintriss Controls Group ULC, doing business as Wintriss ISB. With ISB’s full complement of light curtains, press brake guarding systems such as the Merlin 4000 PRO, and other safety products combined with Wintriss’ Shadow® Light Curtains, the Wintriss ISB acquisition positions the company as a leading provider of safety solutions for presses and press brakes in the metal forming manufacturing industry.
“We are excited to advance the ISB legacy by combining the capabilities of two top safety product companies to form one indisputable leader in metal forming safety control,” said Keith Magnant, President of Wintriss Controls. “ISB has many years of proven expertise in light curtain and press brake guarding technology, making them an ideal fit alongside our leading Shadow Light Curtain line, while further strengthening our combined brands as the preeminent safety solution in metal forming.”
“Joining Wintriss allows ISB to continue innovating in the press brake guarding and safety fields. Reinforced by Wintriss’s reputation for reliability in the metal forming industry, we are thrilled to offer safety solutions to a wider network of metal formers,” said Tony Caruso, Vice President of Sales for ISB. “We eagerly look forward to enhancing the Wintriss portfolio with our extensive line of safety products to jointly become the absolute leader of safety and automation in metal forming.”
Following the Wintriss ISB acquisition, the existing ISB manufacturing facility will continue operating out of Montreal. Further strengthening product support, Wintriss will begin offering the new Shadow 10 Light Curtains in Q1 of 2026 and will service and repair all Shadow 10 light curtains at Wintriss headquarters in Acton, Massachusetts.
