Ducts

Multiduct™ is made from High Density Polyethylene plastic, making it lightweight and easy to install. It is molded using our low-pressure structural foam process. This product is impervious to most underground chemicals. The design flexibility lends itself to straight runs, curves, grade changes and lateral transitions. It is excellent for highway crossings, driveways and railroad right-of-ways. The basic 4, 6, and 9-way ducts can be used in single or stacked multiple formations. The lightweight sections are locked together with fitted spigot and bell ends, sealed with neoprene gaskets and secured with spring clips on all four sides.
