We do our best to make it easy for you to meet your mobility needs; whether you’re driving or just enjoying the ride.

EZ Lock is perfectly suited for both wheelchair seated passengers and drivers. In fact, no other adaptive device provides for more freedom of mobility, or enhances the user’s overall level of independence, than the EZ Lock Wheelchair Docking System does.
