Module Linking:

1. Multiple services or compartments may be obtained

by ganging together up to three single-gang units

(Cat. No. 880MP).

2. For multiple compartment installations which require

pass-through between mating modules, you must

remove the knockout section on adjacent surfaces.

To do this, break away with a hammer making sure

you remove knockouts which will be facing one

another after linking the assembly (see Figure 1).

Knockout tabs are intended for passage

between boxes only. They are not designed

for the attachment of conduit fittings.

3. To assemble the modular units, first apply solvent

cement around the flat mating surfaces of the

adjacent walls and “dovetail” slots (see Figure 1).

Engage the “dovetails” and slide the units together

until seated (see Figure 2).

Concrete Preparation:

4. Cement conduit closure plugs to unused ports

or use conduit reducers if reduction is required.

Knockout must be removed from closure plug

for use on 1/2" trade size conduit (see Figure 3).

5. Secure the box assembly to prevent floating

during concrete pour. For above grade, screw

or nail the assembly to the concrete form. For

on-grade applications, drive stakes or rebar next

to the box and secure with wire. Make sure the

stakes are below the 3 1/2" [89mm] min. screed

line (see Figure 3).

6. Cut conduit to length and cement to ports/reducers.

7. Make sure the box spacer and mud cap are in

place prior to pouring concrete. The interior

spacer and cap prevent any movement of the

box walls during the pour.

8. Pour concrete to desired depth using graduated

markings on the box exterior as a guide.
