The MK5+ is ideal for retrofit or new construction and automates all swing doors up to 4.0 feet wide. It is a header-mounted system, intended for high-traffic, full-time applications. However, the system can be configured for on-demand operation as well. The MK 5 includes a hydraulic closing mechanism which allows it to work as an automatic door closer when the power is turned OFF. This operator is tested to exceed one million full-load open/close cycles. It includes three modular components and can be installed by a single person in an hour or less.
