Starrett 55400 Micrometer Case 2 in 226 226M Micrometers

Product Description

The STARRETT 55400 is a padded protective case designed to store and transport outside micrometers with a maximum measurement capacity of 2 inches. Built with a deluxe padded interior, it cushions the micrometer against shock and prevents contact damage during handling, transport, or bench storage. This type of case is a standard accessory used by machinists, metrologists, and precision measurement technicians who need to protect calibrated tooling between uses. Keeping a micrometer in a dedicated fitted case also helps maintain calibration stability by reducing thermal shock and mechanical stress on the spindle and anvil.

This case is intended for use with the STARRETT 226 and 226M outside micrometers, which have a 2-inch maximum measuring range. It is well suited for shop environments, toolrooms, and field service kits where precision instruments need organized, protected storage. The padded construction makes it appropriate for both bench use and transport in a toolbox or service bag.
