PREPARATION
Single Gang Application
1. Single gang box comes assembled.
Two Gang Application
1. Two single gang boxes are required (2 pieces of E976RFB).
2. Remove the appropriate side of each box to gang them
properly. (Fig. 1) Slide boxes together by aligning the top
interlocking tabs on the side of the base and the bottom tabs
and slots. (Fig. 2 and Fig. 3) THESE BOXES DO NOT SNAP
TOGETHER; THEY SLIDE TOGETHER!
Three Gang Application
1. Three single gang boxes are required (3 pieces of E976RFB).
2. Repeat step 2 under Two Gang Application instructions.
NOTE: When ganging 2 or 3 boxes, you must apply a piece
of duct tape along each side and bottom seam.
(Fig. 4 and Fig. 5)
Before Concrete Pour
1. Set box on level surface with minimum concrete pour of 3
3
#8 x
/4
screws
NOTE: With 31/2" concrete pour, space for cord plug between
electrical device and closed cover is 7/8".
2. Set the box so there is a minimum 1/2" exposure after concrete pour.
IMPORTANT! For above grade installation, provide adequate
concrete thickness under the oor to preserve the re rating of
the oor in accordance with the building codes.
3. Secure plastic cap to oor 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.
Fig. 5
Overlap both outer caps onto center cap and duct tape
both underside seams.
Conduit Connections
1. Use Carlon PVC cement to adhere Carlon Plus 40 or Carlon
4
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)
IMPORTANT! Follow solvent cement manufacturers' instruction and safety precautions.
