- Forms
- One-piece or tiered
- Plastics
- HDPE, PP or PVC
Plastic duct bank spacers, also known as conduit spacers, machined to your conduit layout. For underground duct banks, and for conduit runs in factories and warehouses. Made to your drawing, from a sample or from the layout alone.

Your layout
Spacers machined to your layout
Every duct bank has its own conduit count, sizes and spacing. We machine the hole pattern to match, so each conduit sits in its place and stays there through the pour.
- DIAGRAM: template or grid spacer, flat plate with a full pattern of conduit holes
Template or grid
A flat plate with the full hole pattern, such as 2 × 2, 3 × 3 or your project’s layout.
- DIAGRAM: base spacer with intermediate spacers stacked above, one row of conduit per tier
Base and intermediate
A base spacer sets the bottom row off the trench floor. Intermediate spacers stack above it, one row of conduit at a time.
- DIAGRAM: chair or modular spacers, single-conduit modules combined into a larger layout
Chair or modular
Spacers that hold one conduit or a small group, combined into a larger layout. Useful when conduit count or size changes along the run.

- Rebar clearance slots
- Concrete flow-through openings

How your spacers are made
±0.002"–
±0.005"
On critical dimensions, depending on the plastic. The program for your layout is kept, so a reorder or the next phase matches the first.
-
Milled from sheet, no mold
CNC milled from solid sheet, so a new layout or a drawing change goes straight to the machine. Edges are finished clean, so conduit and cable don’t catch.
CNC milling -
The same layout, every spacer
Each spacer in the run is cut from the same program, so the layout repeats all the way down the trench.
-
One job to repeat programs
A single duct bank, a phased build, or the same spacer on job after job.

The spacing along the trench comes from your project drawings or spec. Give us the count for the run, and we machine that many.
Yes. For a phased build, ask about blanket orders, so each phase’s spacers are ready when you need them.
