JUNCTION BOX AND WALKERDUCT INSTALLATION LAYOUT:
1. Secure bench marks at convenient locations on walls or columns wherever the underfloor duct system is to be
installed. This will help establish the level of the finished concrete floor.
2. Obtain the location of the first duct run from the plans.
3. Stretch a base line, at finished floor level, that corresponds with the center of the duct run.
4. In the middle, and at right angles to the line created in Step 3, stretch another line.
5. These two lines should be used as measuring points for laying out the horizontal and vertical runs of duct.
