Box installation – concrete floor on-grade – Legrand 862 User Manual
Page 2
1. Purchase Kit No. 862KIT.
2. Attach the desired number of conduit
connectors, the mud cap, and gasket
to the 862 Series Floor Box.
3. Determine the needed height the box will sit below or
above the concrete screed line so that a flush assembly
can be achieved once the cover is attached to the box
and the finished tile or carpet flooring is in place. (Use
Table 1 and Table 2 as guides. Pay particular attention to
where the depth of cut measurement is taken – finished
vs. sub-floor.)
4. For mounting on grade, level a
concrete block taking note of the
box height with mud cap and the
desired finished (tile or carpet) floor
height above the screed line.
5. To prevent box from floating during
concrete pour, the box should be
attached to the block. One method
would be to clamp the box to the
block using wire.
6. For additional security, use a small
amount of cement around the box to
lock it in place before the final pour.
