Protect your infrastructure with our durable, tamper-resistant locks and covers—engineered to enhance security and streamline your operations.
Engineered for strength, safety, and ease of use, EJ composite access covers offer a modern alternative to traditional cast iron lids. Lightweight yet incredibly durable, these covers are corrosion resistant, non-conductive, and easy to handle without specialized equipment. Their composite construction reduces risk during installation and maintenance while delivering long-term performance in even the harshest environments. Built for modern utility work, these covers truly shine when combined with a smart, secure locking system.
The TwistLIFT® is a built-in, tamper-resistant locking system designed to keep infrastructure secure without complicating access. With a single-tool operation and no loose parts, this internal mechanism reduces installation time and eliminates the headaches of traditional bolt-down lids. It’s built to resist corrosion, prevent unauthorized entry, and simplify maintenance — all in one seamless system. Designed with field crews in mind, the TwistLIFT® becomes even more effective when paired with the right composite cover.
While each product stands strong on its own, the real advantage comes when the EJ Composite Cover is paired with the TwistLIFT® locking system. Together, they create a complete, low-maintenance solution that delivers security, durability, and ease of use in one integrated package. No more struggling with heavy lids or dealing with missing bolts — just reliable protection and streamlined access, every time. It’s a smart investment that keeps crews safer, systems more secure, and operations running smoothly.
Critical infrastructure systems demand more from access points than ever before. Traditional manhole covers and locking mechanisms often fall short when it comes to resisting tampering, withstanding repeated impact, or preventing corrosion. In high-traffic areas, older systems are prone to rattling, shifting, and even dislodging—creating safety hazards for both the public and utility workers. Environmental exposure further compounds the issue, with moisture, debris, and chemicals accelerating deterioration. Across municipalities, utilities, and industrial sites, operators are left managing access points that are vulnerable, outdated, and difficult to maintain.
Modern infrastructure demands a new standard for access control, and that’s exactly what these advanced locking systems and composite covers deliver. Built to endure extreme traffic loads, resist environmental wear, and stay securely in place, they eliminate the noise, shifting, and vulnerability of older systems. With corrosion-proof materials and a tamper-resistant design, they reduce maintenance demands while enhancing safety for both workers and the public. Whether you’re managing utility vaults, sewer lines, or roadway systems, these integrated solutions meet the realities of today’s infrastructure challenges with reliability you can trust.
Cities and utility providers need access solutions that perform reliably under pressure, resist tampering, and protect critical underground assets. EJ composite covers and TwistLIFT locks meet these demands with strength, security, and ease of use, helping municipalities maintain safer, more efficient infrastructure systems.
Protect wastewater, stormwater, and sewer systems with secure, tamper-resistant covers that hold up under pressure in busy municipal settings.
Shield sensitive communication infrastructure from unauthorized entry and environmental exposure, helping maintain uptime and long-term performance.
Defend underground electrical systems with non-corrosive, heavy-duty locks built for utility-grade conditions and daily operational stress.
Support industrial safety and access control with robust solutions for maintenance holes, tank lids, and below-grade service enclosures.
Perform reliably under traffic stress with load-rated covers that minimize noise, resist shifting, and maintain secure access in high-use environments.
Composite covers offer several practical advantages over their metal counterparts, particularly in environments where corrosion, theft, or maintenance costs are a concern. Since they’re made from non-metallic materials, they don’t rust, degrade, or require coatings over time. This durability translates to fewer replacements and less frequent maintenance, helping municipalities and utilities manage long-term budgets more efficiently.
Beyond durability, composite covers are also significantly lighter, which simplifies handling during installation and inspection. The reduced weight minimizes risk of injury for crews and makes manual access safer and faster. Additionally, because they have little to no scrap value, composite materials deter theft—offering an extra layer of operational security for public and private infrastructure systems.
The TwistLIFT® Lock system is specifically engineered for tamper resistance, using a rotating lock mechanism that cannot be disengaged without the proper tool. This added layer of protection helps ensure critical infrastructure remains secure, even in high-traffic or vulnerable areas. The lock design also helps eliminate issues like accidental dislodgement or improper resealing—both of which can lead to infiltration, system damage, or safety hazards.
Combined with a snug cover fit and engineered contact points, these systems maintain structural integrity while keeping out unwanted access. That’s essential for applications like telecom vaults, power enclosures, and sewer lines, where unauthorized entry can have serious safety or operational consequences. These products are designed not just to lock, but to defend the system as a whole.
Yes, both the composite frames and TwistLIFT® Locks are designed to seamlessly integrate with existing infrastructure. Whether you’re working on a new project or updating older systems, these solutions can be easily installed using standard techniques like the Hang & Pour Method. This eliminates the need for expensive structural modifications or specialized tools, streamlining the upgrade process for contractors and engineers.
When retrofitting, the lightweight nature of the composite materials ensures that installation is quick and hassle-free, even in more challenging environments. This versatility allows municipalities and utilities to modernize aging infrastructure efficiently, keeping projects on track and minimizing disruptions.
