A block, perhaps built up, which fits against the edge of the BEDSTONE while the RUNNER STONE is being turned over. It is secured against moving by bolts or pins engaging with purpose made holes in the floor. The edge of the runner stone rests on the Saddle as it is being turned over and is thereby prevented from slipping. It also protects the floor from damage. the SADDLE is not required when a STONE CRANE and CALLIPERS are used.
