We wanted to share a recent project where our aluminum MRL (modular roof ladder) proved to be an excellent solution for a customer needing safe and long-lasting access to their RTUs and solar panels. They faced a challenge where standard ladders wouldn’t meet OSHA clearance requirements over their gutters.

Our MRL modular ladder addressed these concerns effectively. Constructed from off-the-shelf 8’ and 4’ aluminum sections, these ladders typically ship within 2-3 days, offering a significant time advantage over custom steel ladders, which usually take 4-5 weeks. The lighter weight of the aluminum also meant our installation team could complete the setup without the additional expense of lift equipment.
4′ and 8′ ladder sections in stock
On-site, we were able to trim the aluminum ladder to the precise length needed without any concerns about rust and utilized adjustable bolt-on wall brackets. The adjustable brackets allowed for the necessary 7″ clearance over the existing gutter, as required by OSHA, and provided the flexibility to adjust the bracket’s vertical position to avoid obstructions and find optimal placement.

The adjustability in both climb height and bracket location streamlined the process, removing the need for extra approval drawings and site visits typically required for fully welded designs. Furthermore, all installation hardware is stainless steel, ensuring a secure, quick, and durable solution for the customer.
Understanding their preference to avoid roof penetrations, we supplied weighted bases for the crossover. It’s worth noting that we also offer specialized hardware for various metal roof types, including standing seam clamps for standing seam roofs and solutions for corrugated roofs. For membrane roofs, we provide a customized seal and anchor, though we would need the roof manufacturer and model for proper installation.

For added safety, we installed a self-closing safety gate at the crossover point. A-Mezz can also provide fall arrest systems, as mandated by OSHA for climbs exceeding 24’, and roof railing that integrates seamlessly with the ladder rails for comprehensive worker protection. This railing can be installed directly on the roof, wall face, parapets, or with weighted bases to prevent roof penetrations.
