Plastic Spacers for Duct
Vertical and Horizontal Interlocking
For completely enclosed and locked-in duct banks
·
They snap together vertically for fast, secure fi eld assembly.
·
Only two components, base and intermediate, are needed. Banding is not necessary.
·
With the Vertical-Lock spacer, ducts are accurately separated. Spacers lock fi rmly together, preventing
separation while workmen walk atop the bank.
·
Alignment of the duct bank sections is relatively easy with this completely locked-in construction.
·
To prevent the top tier from fl oating during encased burial, it is suggested that an intermediate spacer
be used as a cap.
·
Used in both EB and DB installations.
·
Vertical and horizontal interlocking permits building a strong, locked-in duct bank. A wide baseplate
provides solid support for heaviest loads.
