LEVELING JUNCTION BOXES PRIOR TO CONCRETE POUR:
1. Manufacturer suggests that boxes be installed on sidewalks or precast concrete blocks when on grade.
2. Install hex nuts to each of the four leveling feet.
3. Thread leveling feet into junction box as shown in Step 2 in above diagram.
4. Standard foot provides approximately 1 1/2" [38mm] upward adjustment.
5. Use leveling feet to adjust junction box top to the finished concrete screed level. Do not use the cover
adjustment screws for leveling at this time.
6. Duct openings, which share a ground clip, must both be filled before the clip is driven in.
7. After all junction boxes have been leveled, care should be taken to insure that they will not be moved during concrete pour.
8. This is accomplished by driving studs or nails through the holes in the leveling feet.
9. When junction boxes and duct are correctly leveled and in final position, drive in ground clips on the junction boxes to
secure duct and provide ground continuity.
10. IMPORTANT: Remove cover plate and adjust the height of any support studs within the box, so that the cover plate rests
on the studs when in place.
CAUTION:
A solid foundation of grout or concrete
must be provided beneath the entire
junction box to prevent excessive
cover plate deflection and damage.
