Are you frustrated by the closers available today that detract from your hardware selection and mill work detail. Then check this out – you will not have to stay up at night any longer worrying whether your concealed closer is adjustable, fire-rated and relatively easy to install. We have been using the Perko closers as a part of our hardware schedules for several years now. A whole lot better than grandma’s spring on her screen door (sorry grandma).
