Flatline Van Co’s 2‑Pack Low Pro Crossbars are engineered to extend the functionality of ProMaster Low Pro roof racks by providing adjustable mounting platforms for accessories. Fully compatible with both 136″ and 159″ high‑roof models, these crossbars integrate seamlessly into the Low Pro system and support loads ranging from food trays to solar panels.
Drawing on a lightweight yet robust combination of aluminum and 80/20 extrusion, the crossbars maintain the rack’s slim profile while enabling flexible configuration. Whether mounting kayaks, rooftop tents, solar arrays, or external gear, the T-slot design simplifies accessory attachment without drilling or modification.
Built with down-the-road expansion in mind, they support Flatline’s awning, lighting, decking, and storage systems. The clean CNC‑finished powder-coated surface complements the rack’s aesthetic and reduces wind noise, all while retaining the structural integrity for gear mounting on adventure builds.
Note: These crossbars are exclusively compatible with the ProMaster Low Pro Roof Rack.
Loosen side rails on the installed Low Pro roof rack. Slide crossbars into desired T-slot positions. Adjust spacing for intended load. Align crossbars perpendicular to van centerline and tighten stainless steel hardware provided. Ensure crossbars are torque-seated per spec. No drilling required—modular install typically completed in ~15 minutes using basic tools.
