DualTrack-T™: The Dual-Channel Cross Bar System for Mercedes Sprinter
One Rail. Two Standards.
Zero Compromise.
The DualTrack-T™ is the first cross bar to run L-Track and T-Bolt channels in parallel across a single extruded profile — purpose-engineered for Mercedes Sprinter.
Pick Your Ecosystem. Live With It.
Every cross bar on the market forces you into a single mounting standard before you've decided what your build actually needs. L-Track or T-Bolt. Pick one. Commit. Hope your plans don't change.
If you've built out a Sprinter — or even started planning one — you've hit this wall. The accessory ecosystem for roof-mounted gear splits cleanly into two camps, each with its own hardware standard, its own connector geometry, and its own catalog of compatible accessories. They don't talk to each other. And until now, no cross bar has tried to bridge them.
L-Track
Also called airline track or logistic track. Uses spring-loaded single-stud fittings that slide freely along the channel and lock at any position. The dominant standard for tie-downs, cargo management, and overlanding slider accessories.
- Slide-and-lock positioning
- Single-stud spring fittings
- Tie-downs, nets, sliders
- Infinite adjustment along rail
T-Bolt
Also called T-slot. Accessories clamp into a T-shaped channel with bolt-and-nut retention. The standard used by major crossbar accessory brands — Thule, Yakima, Rhino-Rack, Front Runner — for carriers, racks, and bolt-on fixtures.
- Bolt-and-nut retention
- Drop-in T-nut hardware
- Carriers, racks, fixtures
- Fixed-position, high-clamp-force
These two systems developed independently, serve different use cases, and have never been combined in a single extrusion profile. Owners who need both — and most builds eventually do — end up running parallel rail systems, stacking adapters, or rebuilding their roof setup from scratch when requirements shift.
That's the problem DualTrack-T was engineered to eliminate.
Dual-Channel Integration: One Extrusion, Two Standards
The DualTrack-T™ is a single extruded aluminum cross bar rail with two independent mounting channels — one L-Track, one T-Bolt — running in parallel across the full usable length of the profile.
This is not an adapter bolted onto a standard rail. It's not a secondary track riveted to an existing extrusion. The dual-channel geometry is integral to the extrusion die itself — both channels are formed in a single pass through the press, producing a monolithic profile with no joints, no fasteners between channels, and no structural weak points at the interface.
Patent Pending Design
The DualTrack-T™ dual-channel cross bar rail profile is the subject of a filed provisional patent application covering the integrated L-Track and T-Bolt channel configuration, the mounting interface system, and the aerodynamic edge profile geometry.
The L-Track channel runs along one face of the extrusion and accepts standard L-Track single-stud fittings — the same spring-loaded hardware used across the aftermarket. Slide a fitting in from either end, position it anywhere along the rail, and the spring detent locks it in place. No tools required for repositioning.
The T-Bolt channel runs parallel along the opposite face and accepts standard T-Bolt drop-in hardware. Insert a T-nut from the end of the rail, slide it to position, and tighten down with a bolt. This is the same interface geometry used by major crossbar accessory ecosystems — mounts designed for T-slot rails work out of the box.
Both channels span the full length of each rail. Both operate independently. Loading, adjusting, or reconfiguring hardware in one channel has zero effect on anything mounted in the other. You can slide an L-Track fitting into position while a T-Bolt-mounted solar panel bracket stays torqued and undisturbed on the opposite face.
Monolithic Extrusion
A single-piece extrusion maintains continuous load paths across the entire cross-section. There are no bolted joints between channels, no riveted adapter plates, and no secondary components that could introduce fastener fatigue or differential thermal expansion. The structural integrity of each channel is a function of the extrusion geometry itself — not the retention of secondary hardware.
Curved-Edge Aero Profile
The outer profile features curved leading and trailing edges that deflect airflow smoothly over the rail body. This is a deliberate departure from flat-top industrial extrusions, which generate turbulence and audible wind noise at highway speeds. Sprinters are daily-driven vehicles — they spend more time at 70 mph on the interstate than crawling fire roads. The aero profile reflects that reality.
Powder Coated Aluminum
High-grade aluminum delivers the structural strength required for distributed roof loads without the weight penalty of steel. The black powder coat finish provides a multi-layer defense against UV degradation, salt exposure, and surface corrosion — engineered for vehicles that live outside, year-round, in every climate zone. The finish is also aesthetically matched to factory Sprinter trim.
End Cap & Bracket Interface
The mounting bracket system interfaces directly with the slot channels on factory OEM Sprinter roof rails, DVA LoadSpan Load-Spreading Roof Rails, or other aftermarket Sprinter roof rail systems. The bracket geometry clamps to the rail channel without drilling — the roof structure is never penetrated, and the install is fully reversible.
Mount Anything. Adapt Instantly.
The dual-channel architecture means the DualTrack-T™ doesn't favor one accessory ecosystem over the other. Both channels accept standard, off-the-shelf hardware. No proprietary DVA fittings required. No adapters. No ecosystem lock-in. Use what you already own, or mix systems freely across both channels of a single rail.
L-Track Channel
- L-Track sliders & single-stud fittings
- Cam-buckle tie-downs & ratchet straps
- Cargo nets (bungee or rigid frame)
- Awning mounts (Darche, 23Zero, ARB)
- Recovery board carriers
- Pelican case brackets
- Quick-release accessory plates
T-Bolt Channel
- Thule / Yakima / Rhino-Rack accessories
- Solar panel mounting brackets
- Light bar mounts (rigid & adjustable)
- Antenna & communications brackets
- Rooftop tent mounting feet
- Cargo basket feet & platforms
- Custom-fabricated T-bolt fixtures
Run both standards on a single rail. Swap gear in seconds without disturbing the opposite channel.
Bolt-On Installation. No-Drill. Fully Reversible.
DualTrack-T™ mounts directly to your Mercedes Sprinter's existing roof rail channels. The mounting bracket system clamps to the slot profile on factory OEM roof rails, DVA's LoadSpan Load-Spreading Roof Rails, or other aftermarket Sprinter roof rail systems. No holes drilled. No permanent modification. Remove the cross bars and the vehicle returns to factory condition.
The no-drill approach isn't just about convenience. For leased Sprinters, fleet vehicles, and vans that may be resold, preserving the factory roof structure has direct financial value. No drill holes means no depreciation argument at turn-in, no body shop visits to close out a lease, and no debates with a buyer about roof integrity. The install is a commitment to capability, not a commitment to permanent modification.
All required mounting hardware ships with every kit. An installation video is available online for reference, though most owners report the process is self-explanatory with the hardware in hand.

Three Builds. One Rail System.
The dual-channel design doesn't just add flexibility in the abstract. It changes how you plan, configure, and evolve a Sprinter roof setup. Here's how the DualTrack-T™ maps across three distinct build profiles — each using both channels simultaneously for capability that a single-standard rail can't deliver.
DualTrack vs. DualTrack-T
The DualTrack-T™ is the second product in DVA Mechanics' Patent Pending dual-channel cross bar platform. Both products share the same core engineering thesis — two independent mounting channels in a single extrusion — but they pair different channel types to match the accessory ecosystems most relevant to each vehicle platform.
DualTrack
Dual L-Track channels. Designed for the INEOS Grenadier. Maximizes slider and tie-down flexibility with two independent L-Track channels — optimized for the heavy cargo management and recovery gear demands of the Grenadier platform.
DualTrack-T™
L-Track + T-Bolt channels. Designed for the Mercedes Sprinter. Bridges both mounting ecosystems in a single rail — optimized for the mixed accessory landscape of Sprinter builds where crossbar accessories and slider hardware coexist.
The channel pairing is the difference. The design philosophy is the same: eliminate forced choices between mounting standards. Give the owner one rail that handles whatever the build requires — today and three years from now when the requirements have changed twice.
The Rail That Doesn't Force a Decision
The Sprinter aftermarket is full of capable products that ask you to choose before you're ready. L-Track or T-Bolt. Sliders or bolt-ons. This ecosystem or that one.
DualTrack-T™ was designed to make that decision unnecessary. One extrusion profile. Two independent, full-length channels. Standard hardware on both sides. No adapters, no proprietary fittings, no compromise between mounting systems that should have been combined a long time ago.
Every DVA product starts the same way: a problem we hit on our own builds, a solution designed in-house, and testing on our own vehicles before anything ships. The DualTrack-T™ is no different. We built it because we were tired of running parallel systems on the roof of a van that deserves better engineering than that.
If it doesn't work on our Sprinter, it doesn't ship on yours.
