Planning
Should I specify TR-900 or TR-500A?
TR-900 and TR-500A publish the same tabletop, rotation, slide travel and chair figures; only the installed envelope differs. TR-900 is 1500 × 1000 × 1990 mm and weighs 175 kg; TR-500A is 1510 × 1000 × 2130 mm and weighs 168 kg. Take TR-900 where overall height is the constraint.
