Handi-Ramp® also offers the Stabilizer Bar, an important new accessory developed specifically to keep Tracks from moving or sliding while in use. The Stabilizer Bar ensures absolute Track System stability for van access or particularly steep applications. To use, simply mount the stabilizer bar on the threshold of a barrier or van doorway, then securely lock each Track down into it. Stabilizer Bars are available in standard lengths. Custom lengths are available upon request.
