Specifications

A
3" Standard for all Base Spacers
(with the exception of the 4X1-S288NFN)
The Spacers and Rebar Holder are designed with a dovetail
tongue-and-groove feature for easy installation.
If required to permanently fix the position of a group of Spacers
and/or Rebar Holder, the following are recommended procedures:
1. Use Carlon
®
Quick-Set Cement glue during assembly or spot glue
after assembly to secure.
2. During assembly, deform the edge of the tongue or groove portion
of the dovetail slide with a pair of pliers or similar tool. This deformation
will create an interference, restricting movement.
3. An assembled system may be wired together for additional support.
Installation Note
Important:
The use of duct spacers for direct burial may result in excessive
point deflections unless proper design engineering is applied, such
as the proper compaction of the appropriate backfill material.
Suggested Specification:
(Duct) (Conduit) bank shall be encased in concrete with at least three inches
of concrete at the top and bottom and two inches on each side. A horizontal
and vertical separation between the ducts of ____* inches shall be
maintained by installing Carlon

and vertical locking intervals of ____** feet.
*Standard Separations of 1", 1
