Values shown are indicative — confirm the required tier against ANSI/SCTE 77 project specifications before ordering. Deliberate road traffic (AASHTO H-20) requires precast concrete, cast iron or other H-20-recognized materials — not composite enclosures.
Common questions
Why composite instead of concrete?
One-piece molding means no seams for water and roots, a fraction of the weight, no crane on site, and no corrosion or grounding requirement.
How many units fit in a container?
Flat-pack design loads up to 280 sets of the 24×36×24 manhole in one 40 ft container — the packing list ships with every quotation.
Can you add cable ports and logos?
Yes. Port knockouts, pigment matching and molded-in logos are done in-house on our own tooling.
What is the lead time?
4 weeks standard production, 2 weeks for samples. Both counted from drawing and material confirmation.
