Wheelchair Mounts L3D

When to I used a Rehadapt L3d wheelchair mount.  This serives is built. entirely around 16 mm tube.  Even though the tube is smaller, they still are remarkably strong. They are perhaps best suited for use with direct access with  standard size tablets.  The L3D mounts have all the same parts and features as the H3D. They are just lighter and smaller. Because they are lighter and smaller, they may be easier to handle but the swing away function does not work as well as the heavier H3D..
