HEAVY DUTY STAIR LIFT: SECTION 3

PREPARATION

DETERMINE OVERALL RAIL
LENGTH
(ONLY IF TRACK DID NOT
COME PRE-CUT TO LENGTH)
1. Determine obstructions that will affect the
position and length of the rail, such as walls,
doors, hallway orientation, etc.
2. Measure the overall length of the stairs from the
nose at the top landing to the floor (nose to floor
measurement). See Figure 3-1.
Figure 3-1
3. For a normal stairway with adequate landing
space, add 7" to the nose to floor measurement.
This will provide enough rail length to allow the
stair lift to be adjusted so that the floor-to-seat
height will be the same at both the top and the
bottom.
4. If the top landing has restrictions (i.e. a wall or a
doorway), use the chart to determine the length
of extensions needed. See Figure 3-2.

joint holes. Remove the charger strips and wire
harness before cutting.
