2" concrete pour, space for cord plug between electrical device
and closed cover is
7

IMPORTANT! For above
grade installation, provide adequate concrete thickness
under the floor to preserve the fire rating of the floor in accordance with the
building codes.
3. Secure plastic cap to floor box before pour by cross taping the cap.(Fig.6)
a. For two gang applications, cut the edge of one cap, then overlap the second.
Duct tape the underside seam.
b. For three gang applications, cut both edges of center cap. Overlap both
outer caps onto center cap and duct tape both underside seams.

1. Use Carlon PVC cement to adhere Carlon Plus 40 or Carlon Plus 80
nonmetallic conduit or Flex Plus Blue ENT (electrical nonmetallic tubing) to
utilized ports.
2. To feed parallel runs of
3

4" conduit use Carlon “Y” adapter E972Y.
3. Use Carlon PVC cement to adhere reducer-plugs (provided with Floor Box) to
seal off unused conduit openings.
4. Floor box sides may be drilled for conduit feeds; to access, stay above
noticeable “scribe lines” on side. (Fig.7)
