This feature is recommended to help eliminate the problem of casting deflection and potential operator error, which can occur with 12" and 18" throat micrometers. In addition, it provides uniform anvil pressure.

The micrometer is foot activated. Unlike motorized units, it can be operated as quickly or as slowly as the operator chooses. With foot activation, both hands are free - a valuable feature when both hands are needed to handle cumbersome materials or when fast production gaging is required.
