CAPITOL TECHNICAL GUIDE v3

OUTSIDE MOUNT 90º CORNER WINDOW
1. Measure outside from the architrave to the back of
where the frame would sit, at the front edge of the
window as shown left.
2. A+B = total window width.
3. This is the size you enter on the order as finish size
4. The total width of A is the location of corner post
5. If a divider rail is required, measure from the floor or
outside of architrave to the centre of the required
divider rail location. Remember rails could vary up
to 40mm if not specified critical.
6. If a T post is required, measure from the outside of
architrave at left to the centre of the T post
7. T post location in area B would be A + Post position
INSIDE MOUNT TRACK BIFOLDS
Headboards are supplied as standard for track bifolds with top track attached. Sideboards and
bottom boards are optional however floor track is mandatory with no option to waive warranty.
Track bifolds can be installed inside mount and standard deductions are taken at the factory to
allow for fitting. If semi recess mount is required with shorter returns, you must specify this in notes.
Ensure there is enough clearance for doorhandles, track layouts are specified on the next page.
1. Measure the recess depth
2. Measure the diagonal to check for squareness.
If the diagonal sizes vary by more than 10mm, an outside mount is preferable
3. Measure inside width in at least 3 places (top, centre and bottom)
4. Provide the smallest width size as window size, do NOT take a deduction
5. Measure inside height in at least 3 places (left, centre and right)
6. Provide the smallest height size as window size, do NOT take a deduction
7. If a divider rail is required, measure from the inside bottom to the centre of the required
divider rail location. Remember rails could vary up to 40mm if not specified critical.
OUTSIDE MOUNT TRACK BIFOLDS
Headboards are supplied as standard for track bifolds with top track attached. Sideboards and
bottom boards are optional however sideboards are recommended for outside mount to
provide better light block. It is common practice to mount headboard and sideboards outside
of the architrave hard up against the wall. For this layout, you will need to add extra to your sizes
to allow for boards. Ensure there is enough clearance for doorhandles. Track layouts are specified
on the next page.
1. Measure outside of architrave width in at least 3 places (top, centre and bottom)
2. Add at least 38mm for sideboards (if required) as finish size
3. Measure outside of architrave height in at least 3 places (left, centre and right)
4. Add at least 19mm for headboard as finish size
5. If a divider rail is required, measure from the floor or outside of architrave to the centre
of the required divider rail location. Remember rails could vary up to 40mm if not
specified critical.
