Super Simplex Dimensions

Use the drawings at right with the charts below to find the stairway dimensions.

Required Information:

1. Floor to ceiling height ("C")
2. Distance from finished ceiling
to floor above ("D")

If "D" is less than 13", the standard box frame will work fine and only CHART 1 is needed.

If "D" is 13" or more, CHART 2 is needed to determine the opening size at the floor above.

CHART 1
C (CEILING HEIGHT)	X (CLEARANCE)	L	Rough opening in ceiling	Rough opening in floor above*
7’ 1” to 8’ 0”	13”	53 ¼”	30” x 54”	30” x L2 + ¾”
8’ 1” to 8’ 9”	14 ½”	53 ¼”	30” x 54”	30” x L2 + ¾”
8’ 10” to 9’ 9”	22”	53 ¼”	30” x 54”	30” x L2 + ¾”
9’ 10” to 10’ 11”	18”	63 ¼”	30” x 64”	30” x L2 + ¾”
11’ 0” to 12’ 0”	26”	63 ¼”	30” x 64”	30” x L2 + ¾”
12’ 1” to 13’ 6”	26”	71 ¼”	22 ½” x 72”	22 ½” x 72”**

* - If box frame is used, this dimension is the same as the ceiling opening.
** - 63° Angle frame is not available for ceiling heights greater than 12

Model Number = SS/AL-"C" where "C" is exact ceiling height.
For additional frame depths (D") on Chart 2, please call the factory.
