What the Retrofit Upgrade Delivers
🔄
Upgrade Without Full Replacement
If your vehicle already has Q'Straint ONE-compatible base infrastructure, the Retrofit kit adds the integrated Q'STRAINT ONE platform without the cost of replacing the entire system. Designed for fleets standardizing across vehicles already partially equipped.
✅
Same ONE System Performance
After installation, operators experience the same push-button operation, audio/visual engagement confirmation, and under-1-minute securement as the full Q11-0000 or Q11-0001 kits. Fleet standardization is preserved regardless of which kit equipped each vehicle.
💰
Lower Cost Per Vehicle
At $1,494 versus $4,661–$5,200 for a full kit, the Retrofit allows fleets to extend the Q'STRAINT ONE platform to more vehicles at a lower per-unit cost when base infrastructure is already present. Call to confirm compatibility before ordering.
Key Features
🔘
Push-Button Operation
Single-button lock and unlock with audio and visual confirmation. After Retrofit installation, operators use the same standardized push-button process as all other Q'STRAINT ONE-equipped vehicles in the fleet.
⏱️
Under 1-Minute Securement
Full 4-point tie-down and occupant restraint in under a minute. After a Retrofit installation, the vehicle meets the same speed and consistency benchmarks as the full Q'STRAINT ONE platform kits.
📦
Integrated Component Storage
All components stored within the platform — no loose straps, no exposed track. The Retrofit brings the same clean, organized vehicle interior as the complete kit.
🎯
Defined Seating Zone
The installed platform creates the same visual seating zone as the full system — operators guide the wheelchair into the defined position without angle guessing or fumbling with floor anchor points.
📱
ONE APPROACH Training
Includes the QR code decal for Q'Straint's ONE APPROACH mobile training system — onboarding videos, scooter securement demo, emergency troubleshooting, and the Securement CheQlist.
♿
Handles Difficult Chairs
Scooters, power chairs, and oversized frames — the Retrofit delivers the same extended device compatibility as the complete Q'STRAINT ONE kit. No special training for non-standard wheelchairs.
⚠ Important — Confirm Compatibility Before Ordering
The Q11-0004 Retrofit is designed for vehicles that already have Q'Straint ONE-compatible base infrastructure installed. It is not a standalone system and requires existing compatible mounting provisions. If you are outfitting a vehicle from scratch, you need the complete Left Hand (Q11-0000, $5,200) or Right Hand (Q11-0001, $4,661) system kit. Call us at 800.884.6456 and we will verify which product is correct for your specific vehicles before you order.

Frequently Asked Questions
▸ How do I know if my vehicle is compatible with the Retrofit kit?
The Q11-0004 is designed for vehicles that already have Q'Straint ONE-compatible base mounting provisions. Do not assume compatibility — call us at 800.884.6456 before ordering. Our specialists work with Q'Straint vehicle installations daily and will quickly determine whether the Retrofit is the right path or whether a complete kit (Q11-0000 or Q11-0001) is required.
▸ After Retrofit installation, does the vehicle perform the same as a full Q11-0001 kit?
Yes — when installed in a compatible vehicle, the Retrofit delivers the same push-button operation, audio/visual confirmation, under-1-minute securement, integrated component storage, and ONE APPROACH training QR code as the complete Q11-0001 right-hand kit. Operators experience no performance difference between Retrofit-upgraded vehicles and full-kit vehicles in the fleet.
▸ I'm outfitting new vehicles. Should I order the Retrofit or a complete kit?
For vehicles without existing Q'Straint ONE-compatible infrastructure, you need the complete Left Hand (Q11-0000, $5,200) or Right Hand (Q11-0001, $4,661) kit. The Retrofit is not designed for from-scratch installations. Call us at 800.884.6456 and we'll confirm the right product before you order.
▸ Is fleet pricing available for the Retrofit kit?
Yes. Fleet pricing is available for orders of 5 or more vehicles. Submit a
