When architects design doors aesthetic, needs is a major consideration. Slim Line covers for door closers
provide a narrow, slim design that improves the look of both the closer
and the doorway. The durable track arms are designed to handle interior door applications while helping the door closer to blend more smoothly into the opening. The design fits within the door and the frame making an invisible closer, again an appealing opening doesn't have to be difficult or expensive. Consult with your hardware manufacturer
early in the design process to find the best combination of function and appearance. Remember that the visual design of a building's openings is very important, so don't allow project budgets and building codes to force aesthetics into the background.
