A Made-in-USA Alternative to Wunpeece Duct Spacers
Innovative Plastics base, intermediate, and clip duct spacers are an American-made alternative to Wunpeece-style interlocking duct spacers — same job, sizes 1"–8", no banding, in stock by the case.
By Innovative Plastics Manufacturing
If your duct-bank spec has been built around Wunpeece-style interlocking spacers, Innovative Plastics offers an American-made alternative that fills the same role: holding underground conduit on a precise, no-banding grid through the pour and backfill. This page explains what “alternative” means here and how to match our line to the spacing your drawings call for.
What we mean by “alternative”
Our duct spacers are an independent product from Innovative Plastics Manufacturing, not a Wunpeece part and not a licensed copy. When we call them an alternative, we mean they belong to the same category of fitting — interlocking, snap-together conduit spacers that build a duct bank without banding — and solve the same problem on the jobsite. They are specified and installed the same way: set a course, drop the conduit, stack the next course.
Always verify the separation, conduit trade size, and spacer interval your project requires against our published size tables and your engineering drawings before substituting any product.
What Innovative Plastics offers
- Base and intermediate spacers — two-piece interlocking spacers molded from high-impact polymer, in 18 sizes covering 2”–8” conduit with 1”–3” separation. They lock vertically and horizontally with no banding or tie wire, and serve both encased-burial and direct-burial banks.
- Clip spacers — lighter, single-tier snap-on spacers in 4-way and 6-way configurations for 1”–2” conduit, where a full stacked bank is more than the run needs.
Both are made in Texas, USA, ship by the case, and can be added to a quote request directly from the product page — a domestic-sourcing angle that matters on federally funded and Buy-America-sensitive work. (Confirm specific Buy America / BABA qualification with our sales team for your project before relying on it.)
Choosing a configuration
- Stacked, multi-row, concrete-encased or direct-burial banks (2”–8”) → base and intermediate spacers.
- Single-tier exposed or underground runs (1”–2”) → clip spacers.
- Spacing interval and separation → taken from your project drawings; see duct bank spacing and how many duct spacers per 100 ft to plan quantities.

Frequently asked questions
- Are Innovative Plastics duct spacers a Wunpeece product?
- No. Innovative Plastics duct spacers are manufactured by Innovative Plastics Manufacturing in Texas, USA. Wunpeece is a separate product line from a different manufacturer. Our spacers do the same job — holding conduit on a fixed grid with an interlocking, no-banding design — but they are an independent product, not a Wunpeece part.
- Do Innovative Plastics duct spacers work the same way as interlocking Wunpeece-style spacers?
- Functionally, yes. Our base and intermediate spacers snap together vertically and horizontally to build a stacked duct bank with no banding or tie wire, the same category of interlocking spacer. Confirm the specific separation and conduit trade sizes your project requires against the size tables on our product pages.
- What sizes do Innovative Plastics duct spacers cover?
- Base and intermediate spacers handle duct trade sizes from 2" to 8" with 1"–3" separation; clip spacers cover single-tier 1"–2" runs. All ship by the case and are made in the USA.
