TODD Head Spanner

GPM Model 122    Price:  $3,189

Product Details

The TODD Head Spanner has a wider range of uses than the Black version because it is used independently by a craniophor. The measuring range is from 0 – 200 mm.

The head is oriented in the Frankfurt plane. As a result the auricular level on the vertical bar can be read immediately on the mm.

Application: The TODD Head spanner has adjustable pins that are inserted into the external auditory canals. At the same level is a hinged arm with which a fixation of the lower orbital rim, and thus an adjustment of the skull in ear-eye-level, is possible. The dipstick scale is designed so that the zero mark coincides with the line between the Poria.

Caution: For cleaning please do not use acetone or acetone-containing cleaning agents.
