Measurements
1. Measure from the outside edge of the column to the face of the gear rack (Fig. 13 and 14). The
standard measurement should be 2 ½" plus or minus ⁄". Take this measurement when the room is
fully extended and again when the room is 3" from fully retracted.
NOTE: For units with non-standard installations, contact the OEM for their specific measurements.
2. Measure the gear racks for parallel. There should be less than ⁄" difference between the parallel
measurements.
3. Check for proper seal engagement (no binding).
4. Check for damage to gear rack.
