Installation
Determine the finished floor level of your building because
your Spitfire Series 700 threshold sits at floor level. There is
only 25mm of cover between the bottom of the door sash
and the threshold.
- Unlock your door and open it to 90 degrees.
- On the inside of the frame, you will see the slotted
top pin
retracting screw. (Image 1)
- Unwinding the screw will retract the top pin into the outer
frame. (The screw will stop unwinding after a few turns)

Beware the door sash will weigh circa 120 KG
- Now tilt the sash towards the keep side and lift the sash off
the base plate.
- Carefully set the door sash to one side and cover it with a
dust sheet or similar.
- Check the diagonal dimensions of the door frame to ensure
the frame is square, then check vertical is plumb and fix
the brackets to the adjoining walling. As a general rule, we
recommend fixing 150mm in from each corner and then at
400mm intervals.
- Please peel back the frame gaskets and fix behind them. We
suggest you remove the lock keep and fix behind the keep.
- Please always fix your door through the frame and do not use
fixing brackets.
- On the threshold, remove the rubber cover strip, fix
through, then replace cover strip.
NB. The outerframe must be COMPLETELY SQUARE AND
PLUMB before replacing sash on the base plate.
Please make sure the rotating pin has plenty of grease and is
spinning effortlessly.
Once the outer frame is secure, lift the door back into the frame
at 90 degrees.
Align the rotating pin with the sash and lean the door onto the
pin. You may need a few attempts to get the spacing right,
but you should feel the sash sliding onto the pin when aligned
correctly.
