Flatline Van Co 47.5-Inch Crossbars for Sprinter Low Pro Roof Rack, 2-Pack

The Flatline Van Co 47.5-Inch Crossbars add mounting span to an existing Sprinter Low Pro Roof Rack, sold as a 2-pack with all hardware included. Each crossbar measures 47.5 inches wide and ships with 8 flanged button head stainless steel fasteners in a black oxide finish. These crossbars fit the Sprinter 144" Low Pro Rack, the Sprinter 170" High Roof Low Pro Rack, and the Sprinter 170" Extended Low Pro Rack.

Expand Your Rack's Carrying Capacity

Adding crossbars to a Sprinter Low Pro Roof Rack increases the number of mounting points available across the roof, giving more surface area for gear, accessories, or cargo management systems. The 47.5-inch span matches the width of the Low Pro Rack platform, so each bar integrates flush with the existing structure rather than sitting proud or requiring adapters.

Hardware That Holds Up to the Elements

Every 2-pack includes 8 flanged button head stainless steel fasteners finished in black oxide. Stainless steel resists corrosion from rain, road spray, and wash cycles, while the black oxide treatment keeps the hardware visually consistent with the Low Pro Rack's finish. Flanged button heads distribute clamping load evenly and sit low enough not to interfere with accessories mounted above.

Ready for 10-Series Accessories

The crossbars are compatible with Flatline Van Co's 10-series accessory ecosystem, so lights, mounts, and other 10-series components can attach directly without additional adapters. Expanding the crossbar count increases the positions available for those accessories along the length of the rack.

Specifications

Who This Is For and Isn't

These crossbars suit Sprinter van owners who already have a Flatline Van Co Low Pro Roof Rack on a 144" standard, 170" High Roof, or 170" Extended wheelbase and want to add mounting positions for gear or 10-series accessories. The rack itself is sold separately.

These crossbars do not fit the Sprinter 144" Low Roof Low Pro Rack. They are an add-on component and are not a standalone roof rack system.

Common Questions

Which Sprinter Low Pro Racks do these crossbars fit?

The Flatline Van Co 47.5-Inch Crossbars are designed for three Low Pro Rack configurations: the Sprinter 144" Low Pro Rack, the Sprinter 170" High Roof Low Pro Rack, and the Sprinter 170" Extended Low Pro Rack. They are not compatible with the Sprinter 144" Low Roof Low Pro Rack.

What hardware is included with the crossbars?

Each 2-pack of Flatline Van Co 47.5-Inch Crossbars ships with 8 flanged button head stainless steel fasteners finished in black oxide. No additional hardware is required to mount the crossbars to a compatible Low Pro Rack.

Are these crossbars compatible with 10-series accessories?

Yes. The Flatline Van Co 47.5-Inch Crossbars are compatible with 10-series accessories, so lights, mounts, and other components in that system can attach directly to the crossbars without additional adapters.

Is the Low Pro Roof Rack included with this purchase?

No. The Flatline Van Co 47.5-Inch Crossbars are an add-on component sold separately from the Low Pro Roof Rack. A compatible Low Pro Rack must already be installed on the vehicle before these crossbars can be added.

How many crossbars come in one order?

One order of the Flatline Van Co 47.5-Inch Crossbars includes 2 crossbars and the 8-piece hardware set needed to install them on a compatible Sprinter Low Pro Roof Rack.
