McKissock breast keyhole caliper 38.0mm diameter with cm marks

Clear, Consistent Dimensional Reference for Keyhole Assessment

The McKissock breast keyhole caliper is a measuring instrument designed to assess dimensions associated with keyhole-shaped openings and related anatomical or procedural references. Its 38.0 mm diameter provides a defined physical reference, while the integrated centimetre marks support direct reading during examination, planning, or documentation. For dental professionals working with precise dimensional comparisons, the caliper offers a straightforward way to establish repeatable measurements without relying solely on visual estimation. Its focused design supports controlled handling and efficient reference checks wherever a keyhole profile or circular dimension needs to be evaluated.

Use Cases

• Measure or compare the diameter of a keyhole-shaped opening using the defined 38.0 mm reference.
• Use the centimetre markings for direct dimensional readings during assessment and documentation.
• Support visual and physical comparison when evaluating keyhole profiles or related circular dimensions.
• Incorporate dimensional checks into dental instrument workflows where a caliper-based reference is appropriate.

Specifications

Care & Handling

• Clean the instrument in accordance with facility procedures and the applicable manufacturer instructions.
• Inspect the caliper and its measurement markings before use for visible soil, damage, or loss of legibility.
• Handle the instrument carefully to preserve dimensional accuracy and the clarity of the cm marks.
• Store in a clean, protected location that prevents contact damage and contamination.

General use; follow facility protocols.
