Architectural Hardware Products:
Heavy Duty Door Closers

LCN Heavy Duty Door Closers

For years, hardware professionals have used terms such as “life cycle costing, “life of the product” and “product value.” They are, of course, talking about products built to perform for many years with little or no service. Independent tests have shown that heavy duty LCN closers go well beyond 10 million cycles, a closer record! But how well will LCN perform after decades of opening and closing cycles on school, hospital, church, corporate building and stadium doors? LCN closers are still going strong after 20, 30, even 40 years of service.
