Duct Donut Spacer
With the
Duct Donut Spacer you can save time and effort. Your duct bank
can be easily pre-assembled outside of the trench. You can also
attain either 1½" or 3" separation with the same
spacer.

Duct
Donut Spacers
- One
style does it all
- Save
up to 40% on labor
- Up
to one third less spacers required on many jobs -- don't
over-order
- Do
more work outside the ditch instead of down inside
- Just
slide them on and you have proper duct spacing in every
direction -- and from sides and bottom of trench
- Cannot
fall or tip over
- Place
them anywhere along the run -- they don't have to be stacked
-- this eliminates danger of shear plane in meeting seismic
spcifications
- Easy
flow of concrete thru spacers in the pour
- Fits
all types of conduit. Sizes for conduits 2, 3, 4, 5, 6
inches
- Snap
out feature allows conversion from 3" separation to 1
1/2" separation.

Duct
Arrangements for 1 1/2" to 2" Separation
The
following are sample duct arrangements of 2 to 6 ducts
for 1 1/2" to 2" separation. For duct arrangements of
more than 6 ducts, we recommend also using our non-metallic
Donut Strapping to ease assembly of the duct bank outside
the ditch. Hold Down Bars are also recommended. |
