- 8× M8 stainless steel sliders (pre-installed)
- Butyl tape seal strip
- OEM-style end caps (2 sets)
- M8 stainless steel bolt kit

No drilling on VS30 (2019+). Other Sprinter models require drilling.
Three engineering decisions, measured in daily use
Full-length load distribution
One continuous extrusion per side. Load on a bracket, crossbar, or tie-down spreads along the rail and into multiple factory roof mount points — instead of concentrating at one spot.
Dual channels — L-Track + 25mm T-Slot in parallel
Two channels run the full length of every rail, side-by-side in the same extrusion: industry-standard L-Track and a 25mm T-Slot channel. Both are simultaneously supported — no switching, no adapters. Standard L-Track studs, rings, tie-downs, solar feet and 25mm T-Slot crossbar feet all bolt in directly.
No-drill factory hole mounting
Bolts through the Sprinter's factory pre-punched roof holes. Butyl tape seals the interface. 60–90 min install, one person, basic hand tools. Reversible.
Three steps. Sixty to ninety minutes. One person.
Thread
Slide pre-installed sliders through the factory pre-punched roof holes — no drilling on VS30 (2019+).
Seal
Apply butyl tape under the rail, seat the rail into position on the roof.
Bolt
Secure nuts from the interior, fit OEM-style end caps, reinstall headliner trim — you're done.

What you can mount
| Accessory | Works with LoadSpan-T? |
|---|---|
| DualTrack-T™ crossbars | ✓ Yes — bolt directly to the full-length rail |
| Solar panels | ✓ Yes — standard L-Track feet and 25mm T-Slot feet both supported |
| Fiamma awnings | ✓ Yes — requires LoadSpan-T plus DualTrack-T crossbars |
| Standard M8 crossbar feet | ✓ Yes — kit includes 8× M8 sliders |
| Cargo baskets / roof boxes | ✓ Yes — via DualTrack-T crossbars |
| L-Track accessories (studs, rings, anchors) | ✓ Yes — direct mount into the rail's integrated L-Track channel |
| 25mm T-Slot accessories (M8/M10 T-slot bolts, crossbar feet, clamps) | ✓ Yes — direct mount into the parallel 25mm T-Slot channel, same rail |
| NCV3 Sprinter (2007–2018) | ✗ No — VS30 (2019+) only without drilling. Other models require drilling. |
Awning note: rails alone carry solar, L-Track, and 25mm T-Slot accessories directly. Awnings need a clamp surface — pair LoadSpan-T with DualTrack-T crossbars and Fiamma-style awnings bolt straight on.

How it mounts
- Pull the roof headliner trim where the factory pre-punched roof holes land (interior access required).
- Lay butyl tape along the underside of each rail at the mounting points.
- Set the rail on the roof, thread stainless bolts from inside through the factory holes, torque to spec.
- Fit OEM-style end caps. Reinstall headliner trim. Done.
Total time: 60–90 minutes, one person, basic hand tools. No drilling into the roof skin. Full walkthrough including headliner trim removal is in the LoadSpan engineering guide.
Common pre-purchase questions
Does this fit my Sprinter?
All 2019+ (VS30) Mercedes-Benz Sprinter vans — 144", 170", and 170" Extended wheelbases, all roof heights (Standard, High, Super-High). Not compatible with 2018 and earlier (NCV3) models.
Do I need to drill into my roof?
No. LoadSpan-T bolts through the Sprinter's factory pre-punched roof holes. Interior headliner access is required to tighten nuts from inside. Butyl tape seals the interface.
What's the actual load capacity?
330 lb dynamic (while driving). This is the same ceiling for Standard, High, and Super-High roof. The rails themselves exceed this limit — your vehicle's roof is the limiting factor, not the rail.
Can I mount a Fiamma awning directly to the rails?
Not directly. Awnings need a clamp surface. For Fiamma-style awnings, pair LoadSpan-T with DualTrack-T crossbars — the awning then clamps to the crossbars.
Will my existing L-Track accessories fit?
Yes. The rail has an industry-standard L-Track channel running its full length. Standard studs, rings, tie-down anchors, and sliding mounts drop straight in.
Does the rail also accept 25mm T-Slot hardware?
Yes. A 25mm T-Slot channel runs in parallel down the same extrusion, full-length, alongside the L-Track. Standard M8/M10 T-slot bolts, crossbar feet, and clamp-on accessories drop straight in. Both channels are supported simultaneously — you don't pick one.
How long does install take?
60–90 minutes with basic hand tools. One person can do it. See the engineering guide for the full walkthrough.
What's the warranty and return policy?
DVA backs LoadSpan-T against manufacturing defects. Unused products can be returned within 30 days. Contact support@dvamechanics.com for warranty claims.

Add DualTrack-T™ crossbars
Rails alone are the foundation. DualTrack-T™ crossbars turn the roof into a mounting platform — same dual L-Track + 25mm T-Slot channels, running perpendicular across the rails. Bolts, slides, and adjusts along the full length of every LoadSpan-T rail.
Fiamma awnings, solar arrays, cargo baskets, and roof boxes all mount to DualTrack-T. Rails alone won't carry them — crossbars are required.
LoadSpan-T™ for your Sprinter
Full-length extruded aluminum. Dual L-Track + 25mm T-Slot channels in parallel. No drilling. Ships free in the US.
