Profile: Door Motion Technologies, Inc. specializes in door automation systems. Our product line includes commercial door, residential door, elevator & lift door operators, and other accessories. Our DURASWING™ MK 5+ full time door 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. Our DURASWING™ MK 4R on-demand door operator ideal for interior & exterior doors up to 4 feet wide that latch when closed. It can operate in either an in-swing or out-swing configuration. The MK 4R unlocks, power opens, holds open, power closes, and re-locks the door. This header-mounted system consists of three modular components for easy installation and service. The MK 4R comes standard with a wireless receiver, providing the capability to operate the door with a variety of hand-held remote transmitters. Up to four separate openers can be controlled by the remote. For example, the remote for a typical residential installation might operate the garage door, front door, plus two other doors for commercial, residential, elevator, and wheelchair lift applications.
