Global Door Controls TC612 Series Door Closer in Duronotic (DU) finish is a high-performance, full-cover closer engineered for demanding commercial and institutional applications. As part of the TC600 Series, this closer provides powerful door control for exterior and heavy interior openings, combining strength, reliability, and a premium architectural appearance.
The TC612-DU offers an adjustable spring power range of sizes 2–6, delivering strong closing force for larger, high-traffic, or exterior doors. It is Grade 1 certified per ANSI/BHMA A156.4 and UL Listed for UL10C positive pressure fire door standards.

Three independent regulating valves precisely control sweep speed, latch speed, and backcheck cushioning for field adjustability and reliable performance.
