These units offer many advantages, particularly in commercial buildings. By keeping the door shut tightly at all times, the closer provides assurance that the door is secure, and has not been left open. It also helps improve energy efficiency while keeping fire and smoke from spreading. These devices can be a challenge to install, so proper tools and planning are key to a successful installation job.
