The ProMaster Side Ladder by Flatline Van Co offers secure, efficient access to your van’s roof rack, whether you’re maintaining solar panels, loading gear, or enjoying a rooftop sunset. Made from durable 1.25″ aluminum tubing with flat, dimpled steps, it delivers stable footing even in wet conditions—an upgrade over round-rung competitors
Designed for seamless integration, the ladder bolts to the Promaster Low-Pro Roof Rack and securely anchors to the vehicle's pinch seam. Its two-piece design keeps shipping simple, and assembly is fast with included hardware and common tools—most installs take around an hour.
Finished in a UV-resistant black powder coat, this ladder is lightweight yet robust—ideal for adventurous builds. All necessary mounting hardware is included, and free shipping to the Lower 48 means you’ll be up on the roof in no time without hassle.
Assemble ladder by joining halves with included couplers. Loosely bolt the top to Low-Pro Roof Rack. Attach bottom using pinch-seam bracket and 3/8" hardware. Drill two ¼" pilot holes through plate and seam, then secure with button-head screws and nylocks. Tighten all fasteners and verify vertical alignment. Expect about one hour install with basic tools .
