Successful wheelchair mounting often depends on how the mount is attached to the wheelchair frame. An optimal base is essential and using extensions might be necessary to solve tricky situations. In this episode, Nadine presents two types of extensions – spacers and the 90° adapter – and shows how to use them. These base extensions are components that are sold separately from the mount and frame clamp. They can be combined with any M3D, H3D and L3D mounting solutions.
