The manipulator arm may be swiveled out of the way for convenience in installing the animal or performing a procedure, then returned to the same point reliably with the aid of the locking face block above the swivel joint. The 51603 Dual Manipulator Lab Standard is configured with 3-dimensional manipulator arms on both sides. The second manipulator arm is properly reversed as to handedness. The 51650 and 51653 include the non-puncture 45 degree ear bars instead of the 18 degree ear bars. They are otherwise identical to the 51600 and 51603.
Optional accessories are available.
