Ladder Series (LD) Systems
Counterweighted, freestanding fall protection systems that provide safe and reliable access up and over elevation changes
The Ladder Series (LD) Systems is a modular system that enables workers to move from one level to another with guardrails on the upper elevation to help prevent a fall to the lower level. Upgrade your system to safely scale parapet walls and other changes of elevation on your rooftop with this fall protection system.
Our Ladder Series (LD) Systems and Fixed Access Ladders are an upgrade to your facility that improves the accessibility of your rooftop for workers to support maintenance and increase productivity.
These rooftop safety systems come engineered on a single pallet; elements of the system are pre-assembled with simple to follow instructions and a singular tool for installation. This freestanding, portable, modular system is constructed with corrosion resistant lightweight aluminum tubing and utilizes counterweighted baseplates. With no rooftop penetration, your roof will remain intact and you will not have to worry about any unexpected leaks.
