Engineered by Light Ring Inc. for the crews, ops managers, and safety directors on real municipal and utility jobsites:
Cones, flashlights, and cover rings mark the hazard. They don’t deliver what crews actually need at the opening:
Most manhole near-misses happen during approach, setup, repositioning, and teardown, when crews are moving equipment past the opening and the access point is the highest-consequence feature on a jobsite never designed for staging.
The Light Ring delivers all four in one system.
This is what an active manhole protection system looks like on a working CCTV inspection: 6,000-lumen illumination, structural barrier, and integrated hose management deploying in a single setup.
What you see in the video is what your crew sees on every deployment. Predictable, repeatable, controlled.
The Light Ring closes the gap between visibility, structural protection, and aerosol containment in a single deployable system.
Cones mark the opening. The Light Ring physically guards it. The aluminum frame seats on the rim and catches a misstep, equipment shift, or stumble before it becomes a fall.
All-aluminum frame. Limited lifetime warranty on the structure.
6,000 lumens on the access point. Crews can read edge distance, ladder rungs, and equipment position through standing water, rain, or low ambient light. Four 1,500-lumen LED modules. Marine-grade waterproof switch.
Jetting sends aerosolized water and debris up through the manhole. The flip-up plexiglass cover contains it at the source. Less crew exposure, less equipment fouling, less CCTV lens fogging.
Flip-up safety cover. Built-in cold-weather clarity.
Jetter hoses, CCTV cables, and rigging lines need a clean pass-through. The integrated roller keeps lines moving while the ring stays stable. Less damage, less snagging.
Integrated hose roller. Abrasion-resistant edge guard.
The Light Ring is named as the Preferred MPS in the industry-standard specification for open manhole protection and fall prevention. The spec defines what real manhole safety looks like, and the Light Ring is built to meet every performance requirement.
Adopt it in your municipality to standardize safety across crews and document compliance for contractors and procurement
One system. Three layers of protection. Built for the way your crew actually works.
Budget is the most common reason crews delay a manhole protection system purchase. It is also the most solvable.
One OSHA-recordable fall injury costs tens of thousands, and you can see the hidden costs for yourself on OSHA’s estimator. The Light Ring is a fixed line item that pays for itself the moment it prevents one, and Light Ring Inc. works with crews on funding paths before price becomes the reason to delay.

Yes. The Light Ring is built to support OSHA-focused safety programs around fall prevention, confined-space access, and traffic control in active work zones. It does not replace required PPE, confined-space controls, or traffic control, but it acts as a single engineering control that addresses the barrier, lighting, and aerosol containment needs at the manhole opening.
Unlike cones or barricades, the Light Ring creates a secure, illuminated barrier directly over the manhole opening. This reduces fall risk, improves visibility at night or in confined spaces, and provides a more reliable safety solution during active inspections and maintenance.
The Light Ring can replace or significantly reduce the need for cones, temporary lighting, and makeshift barriers by combining multiple safety functions into one device. Many crews use it as their primary manhole protection system during active work.
An illuminated manhole protector is a safety device that combines high-visibility lighting with a physical barrier to help prevent falls and unauthorized access around open manholes. It improves visibility in low-light conditions while clearly marking the opening for both workers and the public.
Yes. Light Ring Inc. offers a rental program at $250 per week with up to $1,500 in rental fees applied toward purchase. Crews can prove the system on real jobs before committing capital, which makes it easier to justify the budget line item internally.
Yes, the Light Ring’s flip-up plexiglass safety cover helps reduce exposure to aerosols generated during jetting and cleaning operations. This added barrier supports safer working conditions while maintaining visibility for inspections.
The Light Ring is designed for municipal crews, utility departments, public works teams, and contractors performing sewer inspection, jetting, maintenance, or emergency response work. Many municipalities may also be eligible for safety grant funding to support investments in improved manhole protection systems.
The Light Ring fits standard manholes ranging from 22 to 30 inches in diameter and is powered by DeWalt or Milwaukee battery platforms. This allows crews to deploy it quickly without the need for cords or external power sources.
