There are dozens of companies in the United States that convert standard minivans and full-size vans into wheelchair accessible vehicles (WAVs). The three names most buyers search for — BraunAbility, VMI (Vantage Mobility International), and RollX Vans — represent a large share of the market, but they're not the only players. Freedom Motors, ElDorado National, Driverge, and MobilityWorks each serve distinct segments of the private, commercial, and NEMT fleet space.

What they all have in common: every wheelchair accessible vehicle sold in the United States must include a wheelchair securement system that meets WC18 standards and SAE J2249 testing criteria. The floor track system installed by the conversion company determines which tie-down straps and retractors you can use — both now and when you need to replace worn or damaged components.

How Conversion Van Floor Systems Work

Virtually every modern wheelchair accessible van uses one of a small number of floor anchorage systems. Understanding which system your van has is the key to sourcing the right replacement straps, upgrading your securement, or adding capacity for additional passengers.

The most common systems you'll encounter are:

• L-Track (also called airline track): Aluminum extrusions bolted into the van floor. Tie-down hooks slide into the track and lock at any point along its length, providing flexible wheelchair positioning. Compatible with both Q'Straint and Sure-Lok when using OMNI-approved hardware.
• Slide N' Click: A pocket-style anchor built flush into the floor. Compatible with both Q'Straint and Sure-Lok systems. Common in many factory-installed conversions.
• Fixed-pocket anchorages: Pre-set mounting points drilled and anchored at specific positions. Less flexible than track-based systems but extremely durable.
• QLK docking systems: Automated wheelchair docking used in fleet and NEMT applications where rapid, hands-free securement is required.

Two rules apply to every van, regardless of brand or floor system — and understanding the difference between them matters when it's time to order:

• Replacing a single retractor or strap component? Always replace with the same brand already in your system. The hardware connections within a 4-point set are engineered to work together, and a single mismatched component is not a tested configuration.
• Replacing the entire 4-point kit? You have more flexibility. If your floor uses L-Track or another OMNI-certified anchor, you can choose Q'Straint, Sure-Lok, or AMF Bruns — as long as the end fitting on the new kit is compatible with your floor anchor type. All four tie-downs in the new set must be from the same brand.

Occupant restraints are a separate and critical consideration. The lap and shoulder belt assembly that secures the wheelchair user — not the wheelchair itself — uses brand-specific hardware connections. You cannot substitute a Q'Straint occupant restraint into a Sure-Lok system, or vice versa. The buckle and attachment hardware are not interchangeable between brands. When replacing an occupant restraint, you must match the exact brand already installed in the vehicle.

The Major Conversion Van Brands — and What They Use

Side-by-Side Compatibility Overview

* "Full kit only" means the brand can be used when replacing the complete 4-point tie-down set. Single component replacements should always match the brand originally installed. Occupant restraint hardware is always brand-specific — see section below.

Which Tie-Down Straps Do You Need?

Once you know your floor system, matching the right securement product is straightforward. For the large majority of BraunAbility, VMI, RollX, and other conversion vans on the road today, the following securement families are the correct fit:

For L-Track Vehicles (VMI, RollX, Freedom Motors, ElDorado, Driverge)

L-Track is the most versatile system and supports the full range of Q'Straint QRT, Sure-Lok, and AMF Bruns products. All three brands manufacture L-Track-compatible tie-downs that are WC18-certified and appropriate for both private and fleet use. When replacing the complete 4-point kit, any of these three brands is a valid choice — pick the one that best fits your operating environment, replacement availability, and existing occupant restraint hardware. Our Q'Straint tie-down collection, Sure-Lok securement systems, and AMF Bruns tie-downs are all available for L-Track applications.

For BraunAbility Slide N' Click Vehicles

BraunAbility vehicles with the Slide N' Click floor anchor system are designed to pair with Q'Straint QRT-series retractors. Replacement Q'Straint straps for BraunAbility are a direct swap and should be sourced from a WC18-certified supplier to ensure crash test compliance is maintained. Explore our Q'Straint securement systems for compatible options.

AMF Bruns for Any L-Track Van

AMF Bruns is the third major WC18-certified securement brand and an equally valid option for any van running L-Track. Their tie-down systems use standard L-Track end fittings and are compatible with all the major conversion platforms listed in this guide. If you're replacing a complete 4-point kit and your van uses L-Track, AMF Bruns is a direct, code-compliant option alongside Q'Straint and Sure-Lok. Browse our AMF Bruns securement collection for available options.

For NEMT and Multi-Position Fleet Vans

If you operate a fleet vehicle from Driverge, ElDorado, or a high-capacity RollX or VMI commercial build, look for commercial-rated retractors with heavy-duty housing rated for high-cycle use. The QRT360 and SURE-LOK commercial retractor series — as well as AMF Bruns commercial options — are designed for exactly this application.

Mixing Brands: What's Allowed and What to Verify

A complete wheelchair securement system has two distinct components: the wheelchair tie-down straps (the four straps that anchor the wheelchair frame to the floor) and the occupant restraint (the lap and shoulder belt system worn by the wheelchair user). These attach to the vehicle independently and serve different functions.

In some configurations, components from different brands can be used together — for example, Q'Straint retractors paired with an AMF Bruns occupant restraint. However, compatibility is not automatic. It depends on the specific products, your floor mounting system, and your vehicle layout. In occupied transport, always confirm that your occupant restraint is appropriate for the securement hardware and vehicle setup before mixing brands. When uncertain, a matched single-brand system is the lowest-risk approach from both a safety and liability standpoint.

A note on BraunAbility: While BraunAbility vehicles use Q'Straint securement systems, a small number of BraunAbility replacement parts are Q'Straint-manufactured components sold exclusively through BraunAbility — they are not available through standard Q'Straint distribution channels. If you are sourcing a replacement for a specific BraunAbility component and cannot find it through a general Q'Straint supplier, contact BraunAbility directly or an authorized BraunAbility dealer to source the correct part.

How to Identify Your Securement Components: The Required Label

Every WC18-compliant wheelchair tie-down strap and occupant restraint is required to carry a permanent label identifying three key pieces of information:

• Manufacturer name — the brand that made the component (Q'Straint, Sure-Lok, AMF Bruns, etc.)
• Date of manufacture — the month and year the component was produced
• Part number / SKU — the specific model or part number for that component

This label is your single most reliable resource when ordering a replacement part. Before you call a supplier or search online, locate the label on your existing strap or occupant restraint — it will tell you exactly who made it, when it was made, and which part number you need. This is especially important for BraunAbility vehicles where some components must be sourced through BraunAbility specifically, and for older vehicles where the original securement brand may not be obvious from a visual inspection.

Labels are typically found on the webbing near the retractor housing, on the strap body itself, or on the belt tongue of the occupant restraint. If the label on a strap is worn, faded, or missing, that strap should be replaced — a component you cannot positively identify should not remain in service.

The Role of NMEDA in Conversion Van Safety

The National Mobility Equipment Dealers Association (NMEDA) sets industry standards for WAV dealers and conversion companies. When you purchase from a BraunAbility dealer, a VMI-certified dealer, or a RollX-authorized location, you're working with an organization that has agreed to NMEDA's Quality Assurance Program (QAP) guidelines.

NMEDA membership doesn't govern the specific securement brand installed in the vehicle, but it does require that any wheelchair securement system installed meets federal FMVSS guidelines and, for vehicles used in passenger transport, WC18 / SAE J2249 crash testing requirements. This is why you should only replace worn or damaged tie-down straps with certified WC18 securement systems — not generic cargo straps or uncertified products.

When to Replace Your Wheelchair Tie-Down Straps

Regardless of which conversion van brand you operate, the same replacement thresholds apply to the securement hardware:

• Any visible cuts, fraying, or webbing damage — replace immediately
• Retractor mechanism that doesn't lock or retract consistently
• Hook latch that doesn't click securely or shows signs of deformation
• Any strap involved in a vehicle accident, even with no visible damage
• Straps that have exceeded the manufacturer's recommended service life (typically 3–5 years for high-use fleet environments)

NEMT operators and paratransit fleets should conduct documented strap inspections as part of a regular pre-trip checklist. See our full guide on how to inspect and maintain wheelchair tie-down straps for a step-by-step protocol.
