Atlas and Superior Models Only Cutting Stairs to the Proper Length
✎ Trim the stairs only after the floor beneath the stairs is finished . Adding or removing carpet or other flooring material will change the measurements for the length of the stairs .
Step 1 Fully extend the folding section of the stairway . Press down on the stairs to ensure full extension .
Fold the bottom section of the stairway under the middle section , so that the top and middle sections form a straight line ( Fig . 7 ).
Measure distance A and mark the distance on the A side of the bottom stringer . Measure distance B and mark the distance on the B side of the bottom stringer ( Fig . 7 ). Draw a straight line between the points . It is possible for the landing area to be uneven , so repeat this procedure on the other stringer .
Cut each bottom stringer to the proper length , along the lines drawn . The bottom section of the stairs should fit flush with the floor on both sides after cutting .
Check to make sure the stairs fit flush with the floor and that all joints are tight with no gaps ( Fig . 8 ). If the stairs are too long ( Fig . 9 ), trim them again . If the stairs are too short ( Fig . 10 ), do not use them . Contact your vendor or The Marwin Company .
Do not use the stairway unless the stairs fit flush with the floor , and the joints are tight with no gaps .
See Separate Instructions for the Titan ( Aluminum ) Stairway .
Trimming the Stairway Opening
Step 1 Select a moulding and trim around the stairway opening . Allow a gap of approximately 1 / 8 " between the plywood panel of the stairway and the moulding .
