*Ex: 30" less
3
/4" equals 29
1
/4" divided by 2 or 14
5
/8" each door.
Above dimensions do not allow for paint thickness!
STEP 3 - Drill holes
7
/16"
dia. x 1
1
/2" (min.) deep, the
distance from edge of
doors shown, (A) tap top
and bottom pivots into
holes with light hammer
blows, (B) Screw hanger
T-nut in position and turn
hanger into T-nut as far as
possible. (Crimp in T-nut
acts as lock nut.)
FOR 2 OR 4 DOOR INSTALLATIONS
UP TO 50 LBS. Ea (max. two doors to a jamb)
STEP 1 - DOOR HEIGHT - make 2
1
/4" less than finished
opening height. (Allow added clearance for carpeting
thickness.)
STEP 2 - DOOR WIDTH - subtract the following from net
opening width and divide by number of doors;
Ex: 9
1
/2 doors (9 full and 1 half) in 120" net opening -
(1) FOR FULL SIZE DOORS: From net opening width
subtract total of 1
5
/8" for first pair plus
1
/16" for each
additional pair, then divide by total number of doors.
1
5
/8" plus
1
/4" (
1
/16" x 4 pr.) = 1
7
/8". 120" - 1
7
/8" = 118
1
/8" ÷
9
1
/2 or 12
7
/16" each full door.
(2) FOR HALF DOOR: Take
1
/2" of full door plus 1
1
/4".
12
7
/16" ÷ 2 = 6
7
/32" + 1
1
/4" = 7
15
/32".
CENTER HUNG TO BOTH JAMBS - Figure to each jamb
separately using one half OVERALL net opening width.
STEP 3 - Drill pivot and T-nut holes same as Step 3 left hand
column, except that all holes should be 1
1
/4" from door edge in
accordion installations (more than two doors to a jamb).
Ex: 10 doors in 120" net opening -
3
/8" plus
1
/4" (
1
/16" x 4 pr.) =
5
/8". 120" -
5
/8" = 119
3
/8" ÷ 10
or 11
15
/16" each door.
EDGE HUNG TO BOTH JAMBS - Figure (as above) to
each jamb separately using one half OVERALL net
opening width.
CENTER HUNG TO ONE JAMB - One HALF door required
with ANY number of full size doors, providing hangers are
placed on every door starting at lead or center door.
FOR ACCORDION DOOR INSTALLATIONS
UP TO 30 LBS. Ea (more than two doors to a jamb)
STEP 1 - DOOR HEIGHT - make 2
1
/4" less than finished opening
height. (Allow added clearance for carpeting thickness.)
STEP 2 - DOOR WIDTH -
EDGE HUNG TO ONE JAMB - Any EVEN number of same
size doors may be used, providing hangers are placed on
every other door.
From net opening width subtract the total of
3
/8" for first
pair of doors plus
1
/16" for each additional pair of doors.
Then divide by total number of doors.
