This leveling system is specifically made for the Belshaw donut machines. The blocks are used for leveling your machine for optimum operation AND keeping your machine stable and secure during travel. Each block is made of machine aluminum and coated with an anti-corrosion coating. This system will mount permanently to your table and the machine will sit within the containment blocks giving you the flexibility to easily lift the machine off the table for cleaning. When your machine is in the blocks and strapped down, it will not move during travel. It is fully secure from moving in any direction. The block system comes with everything you need to install - except hand tools. Each system will come with 6 blocks, 2 bungees, and hardware for thin table tops (< .5").  If you have a thicker table top, please order the Thick Table Option. (tabletops greater than 1" thick will get longer adjustment knobs)
