The seca 216 has a variable scale with a range of 1.4” to 90” that is inserted into a 55.3” frame. The plastic frame is simply mounted on the wall at the desired height. As the user can choose the range shown in the frame, the seca 216 is suitable for measuring children or adults. The results are clearly displayed in a window on the side of the rod and held in place by the locking screw on the head piece.
