Step 3 Insert combination bracket inside of housing. Mount to

base with four #10-24 x 5/8" [15.9mm] Phillips drive machine

screws. If compartments (A) and (B) are used for different services,

then one or both tunnel blocks must be pressed into the

combination bracket to block the passage of wires between the two

compartments. If pass-through is required between compartments

(A) and (B), tunnel blocks are not needed. Pass-through is available

only between compartments (A) and (B).

Step 4 Secure box to subfloor using wire or nails through the slot adjacent

to the adjusting screws. Once positioned, connect conduit to

adapters.

Step 5 Leave receptacle brackets in shrink wrapping and inside box until

concrete is set and receptacles are ready to be installed.

Step 6 Insert unused tunnel blocks into fingers of combination bracket.

Place brackets in box and insert mudcap on top of blocks.

WARNING: Pour concrete to 1/16" [1.6mm] above box

housing. Pours of 1/4" [6.4mm] or more over

box housing will make it difficult to breakout

the mudcap and cause excessive spalling.

Legrand/Wiremold electrical systems conform to and should be properly

Step 3

Step 1 Determine box location and conduit layout. Remove knockouts and attach proper

conduit adapters (not included) to steel base.

Step 2 Select internal compartments of box which are to be used for power. Service

isolation may be acquired by plastic housing. Power compartments must be

arranged adjacent to one another to utilize the “pass-around” tunneling system (see

Figure 1).

Step 3 Slip housing over base. Insert retaining bracket inside housing and secure to base

using four #10-24 x 3/16" [4.8mm] screws provided (see Figure 2).

Step 4 Adjust box so that top of housing is 1/16" [1.6mm] below screed line using the

leveling screws provided. Secure box to subfloor using wire or nails through the

slots adjacent to the adjusting screws. Once positioned, connect conduit to fittings.

Step 5 Leave receptacle brackets in plastic bags until concrete is set and receptacles are

ready to be installed. Place brackets in box and insert mudcap.

NOTE: Make sure proper compartments are isolated before concrete

placement as barriers must be broken out rendering the barrier

useless and possibly breaking the plastic housing
