Get back on the job fast. Order standard and custom adjustment risers online or over the phone to get heavy-duty cast iron delivered straight to your staging area.
Maximize your project budget. We offer specialized contractor pricing and deep volume discounts on full pallets of steel and precast concrete grade rings.
Our warehouse counters serve the unique needs of municipal paving crews. Find exactly what you need, from expert DOT spec advice to in-stock catch basin frames.
Learn best practices for minimizing jobsite risks and ensuring your adjustment risers meet local DOT load ratings.
Get step-by-step tips from the foundry on setting, sealing, and expanding heavy-duty cast iron frames.
See how our direct-to-site delivery helped municipal road crews overcome tight resurfacing deadlines.
Maintain seamless urban traffic flow. Our heavy-duty solid risers allow for precise manhole elevation adjustment during road overlays, eliminating the need to dig up and rebuild the entire structure.
Rated for H-20 heavy traffic loads.
Supplying municipal scale projects.
Ditch the mortar bed. Our expandable mechanical risers feature a built-in turnbuckle linkage that locks directly into the existing manhole frame. Twist to expand, lock it in, and pave right over it.
Expands outward to bite into the base frame permanently.
Paving crews can lay asphalt immediately after installation.
Roadwork requires more than just round manhole adjustments. We fabricate heavy-duty steel and cast iron rectangular risers designed specifically to raise storm grates and curb inlets to final grade.
Fully enclosed or D-shape profiles for curb abutments.
Engineered for flat grate elevation in highway shoulders.
Roads are rarely perfectly flat. When resurfacing requires accommodating road crown or grade changes, standard flat risers cause manhole covers to sit unevenly. Our custom-tapered rings ensure a perfectly flush fit.
Custom sloped from 1% to 15%+ grades.
Ensures covers sit flush, preventing plow blade snags.
Transitioning from passive iron to active intelligence. Our next-generation risers and frames integrate seamlessly with municipal data networks, transforming standard access points into a real-time diagnostic grid.
Equip your highest-risk flood zones with our smart grates. Using low-power wide-area networks (LPWAN), these units autonomously report flow rates and blockage risks, allowing public works to deploy clearing teams exactly where needed, when needed.
Specially milled access configurations designed to accommodate automated subterranean survey crawlers without human entry.
Optional embedded sensors transmit real-time data on water levels, toxic gas buildup, and temperature directly to municipal dashboards.
Machine learning algorithms analyze micro-stress and traffic load patterns over time to predict fatigue before a structural failure occurs.
Our foundries utilize AI-guided robotics for 100% automated pouring and milling, ensuring zero-defect tolerances down to the millimeter.
Smart access frames detect unauthorized lid removal or tampering, immediately alerting central security networks for critical utility vaults.
