An articulating support arm, an articulating support arm and baseframe in combination and a method of installing an articulating support arm on a baseframe are described. The baseframe and the support arm have corresponding interlocks thereon. The interlocks can be engaged or disengaged by appropriately bringing the support arm into contact with the baseframe. When the interlocks are engaged with one another, the support arm is held in position by the interlocks to allow fasteners to be inserted to lock the support arm and baseframe together and prevent the interlocks from disengaging.
