The seca 222 mechanical telescopic measuring rod is especially developed for wall mounting, and is aligned to work exactly to the millimeter from head to toe up to 90 inches x 1/8″ (228.6 cm x 1 mm).  Its broad measuring slide and heel positioner are professional prerequisites. The telescopic measuring rod ensures that the result can be easily read at eye level even for the tallest patient. When not in use, the measuring slide can be folded down for safety.
