Spectra Products 

Based in Toronto, Canada, Spectra Products Inc. is a company incorporated in 1994 that specializes in the manufacturing and marketing of transportation safety equipment for buses and trucks across Canada and the United States. (The company operated as Spectra Inc. until its name change in January 2020.) They supply brake and wheel-end monitoring systems to the aftermarket, reaching customers through transportation dealers, distributors, and direct sales to fleet operators. Their product portfolio features "Brake Safe," a visual brake stroke indicator system enabling drivers and maintenance teams to quickly assess the brake adjustment status of air-braked trucks, trailers, and buses. Another offering is "Brake Inspector," an electronic in-cab air brake diagnostic system. Additionally, Spectra Products Inc. provides "Termin-8r," an anti-corrosion spray lubricant; "Zafety Lug Lock," designed to prevent wheel-end lug nuts from loosening and thereby averting potential damage or loss; "Hub Alert," a heat-sensitive label for wheel hubs on various heavy-duty vehicles that provides an early warning of critical temperature thresholds; and the "Anti-Seize Cotter Pin," engineered to prevent clevis pins in slack adjusters from seizing.
