The Able Table was made to conform to the room for whatever you plan to do in that space. The advantage of this table is to be able to move them around and let them attach themselves magnetically. The tables were raised up due to caster wheels that were installed for ease of movability. The locking mechanism is used to keep the tables from moving and creating a bigger work space if needed. The tables were built to look like the original but it was built a lot stronger than the original.
