Types of Horizontal Lifeline Systems

At MCL Height Safety, we specialize in the supply, consultation, design, and professional installation of Kee Line® systems across a variety of work environments. Our team ensures each system is customized and installed for maximum safety, compliance, and operational efficiency.

Membrane Roofs

Kee Line® is one of the few systems offering upright posts that can be seamlessly weathered using a standard pipe detail — an ideal solution for membrane roof applications.

Structural Roofs

The Kee Line® structural posts offered by MCL Height Safety are engineered for direct tie-back to the building frame. These heavy-duty anchors can be welded, wrapped, or clamped to steel beams, or mounted directly into concrete — ensuring long-term durability and security.

Structures

Perfect for concrete, steel, brick, or stonework, Kee Line® for Structures provides versatile horizontal lifeline components that can be mounted in both horizontal and overhead configurations.

Metal Sheet Roofs

Designed for fast and simple installation, Kee Line® brackets can be adapted to standing seam metal roofs using the same trusted components as other Kee Line® roof systems.

Overhead

Ideal for tasks such as overhead crane access, vehicle loading, machine maintenance, and industrial cleaning, the overhead Kee Line® system supports up to two users by placing the lifeline directly above the working area for optimal fall protection.

Non-Penetrating

Where roof integrity must be preserved, Kee Line® offers a non-penetrative solution. Using weighted bases instead of fasteners, this system ensures a permanent and secure fall protection setup without compromising the roof structure.

Frequently Asked Questions

How is this horizontal lifeline better than other systems?

The Kee Line Horizontal Lifeline system is technically superior since it’s engineered to immediately absorb energy to minimize impact. The energy absorber is calibrated to impart lower forces into the system in a minor fall. In the event of a more severe fall, the forces are ramped up gradually, providing more stopping power.

Is the Kee Line® price competitive to other horizontal lifeline systems?

Yes. The Kee Line® Horizontal Lifeline system, when backed by the Kee Line® Calculator, immediately provides a materials list so you have an optimized system with in-stock components that is easy to install. This saves you time, money and less labor costs on-site. All components are ISO 9001 assured and made from galvanized, corrosion-resistant steel for long life on the roof.

Are the Kee Line® components in stock?

We offer low lead-times for increased productivity. Kee Line® inventory is always in-stock, which means prompt delivery and no down time waiting for materials so you can get the installation completed quickly.

What does the Kee Line® calculator do for installers?

The Kee Line® Calculator provides both installer and customer with the safest system in the field. It also provides a complete list of components for the entire installation. The calculator does all the math for you and provides alerts if there are any improper calculations. This eliminates risk. Finally, the calculator ensures the HLL system is compliant with OSHA and ANSI regulations and is part of a complete personal fall arrest system that maintains a safety factor of at least two.
