RKG-4 Entry Door Upright Conveyor makes easy work of installing sidelight panels in steel, fiberglass, or wood door units with sidelights, or patio door units.

The RKG-4 is designed to receive assembled door units in a vertical orientation from the RKG-3 Tilt-Up Machine. The door unit is tilted all the way up and over to 6 degrees past vertical so the unit is leaning on the exterior side. In this position the door unit is easily rolled to the clamp station. At this station the door unit is clamped against a fence that holds the door unit vertical so the door can be opened. The RKG-4 is also equipped with a momentary sill clamp release, so the frame can be squared to the door before the sidelight panels are secured. This ensures that the frame will be square after the sidelights are installed.

The RKG-4 is also equipped with a special clamping system that will press the sidelight panels into the sealing compound. The clamps are air-actuated and are controlled by a single push/pull valve, enabling one operator to easily and safely install each sidelight panel. After the panels are seated, the operator can open the door to secure the sidelight panels through the mull posts. After the sidelight panels have been installed, the door unit is unclamped so it is leaning against the brick mold. In this position the door unit can easily be rolled to the next station.

The standard machine will accommodate doors 6’8” high and doors that vary in width from 2'6” to 3’0”.

With the 8’0” door capacity option, the machine can be set up to accommodate doors that vary in height from 6’6” to 8’0”. To change the machine to accommodate different height doors, the entire upper guide assembly and clamps are raised or lowered by turning screws at four locations. For 8’0” high door units the operator will need a movable platform of some type to reach the tops of the door units. The platform unit is not included. The RKG-4 will accommodate jambs up to 6-9/16” wide.
