990-F4 Rendering

The 990-F4 Door Machine is a high-speed prehung station capable of machining 6’8” doors with three hinges and 8’0” doors with four hinges. Changeover from one door height to the other takes only a couple of minutes and requires no tools. For even greater flexibility, the 990-F4 can be equipped with the optional Six-Shooter to install 3½” × 3½” hinges, as well as the optional Eight-Shooter for attaching 4” × 4” hinges. This machine is generally used in conjunction with the Handler Door Feeder, 700-C Assembly Door Machine with 8’0” door capability, and the 960-3 Strike Jamb Router.

Designed for both interior and exterior doors and jambs the 990-F4 will accommodate 1⅜” and 1¾” thick doors from 18” to 48” wide, and either 6’8” or 8’0” in height. The machining sequence includes automatic routing of either 3½” or 4” hinge pockets on both the door and jamb and complete cylindrical lock machining, including faceplate. Cycle time is approximately 10 seconds. Hinges may be attached manually or with the optional Six-Shooter or Eight-Shooter Screw Gun while the door and jamb remain clamped in position. Door-to-door productivity, including hinge mounting, is typically 35-50 seconds.
