I use Lcn Products because Lcn sets industry standards for quality, durability and innovation in premium door closers. Founded in 1926, Lcn became a division of Ingersoll Rand in 1974 and today offers a broad line of products, including heavy-duty closers for interior and exterior doors, with fire/life safety closers/holders and high security manual closers available in most configurations. Lcn also provides power operators and closers for use by people with physical challenges. These innovative door closers offer a wide range of applications in schools, healthcare facilities, sports arenas, government and commercial settings.
