KVAL's 990F-3
(6-8) door pre-hanging system, equipped with the options
for automatic door positioning and the Six-Shooter Screw
Gun, is one of our most popular models of Interior Door
Pre-hanging systems.
The typical cycle time to machine the door and jamb for
three hinges and lock, and attach three hinges is 40 to 55
seconds. This machine is generally used together with our
Handler Door Feeder, 700-C Assembly Table, and the 960-3
Strike Jamb Router. When doors wider than 3-0 need to be
machined, either the Kval ON-2 Door Feeder or ON-3 Door
Feeder needs to be used.
The standard 990F-3 is designed to accommodate interior,
1-3/8 thick and exterior, 1-3/4 thick doors and jambs.
Hinge size changes between 3-1/2 x 3-1/2 and 4 x 4 are
easily done without the use of any tools. The vertical
adjustment is made with top and bottom turrets that are
pre-set to customers specifications. The horizontal size
adjustment is made with two 1/4" long pins that are either
removed or installed as needed. Two to three minutes are all
that are needed to remove the safety covers, make the hinge
size change, and reinstall the safety covers at each head.
KVAL is also pleased to offer as an option the ability to
switch the hinge size on all (3) hinge routers
simultaneously, with one switch on the control panel. With
this option the hinge size change takes less then 5 seconds.
