Insize 3205 Outside Micrometers With Extension Anvil Collar
The Insize 3205 Outside Micrometer with Extension Anvil Collar is built for measuring very large diameters using a single frame with interchangeable anvil collars, rather than requiring a separate micrometer for each range. By adding or removing anvil collars, one 3205 unit can cover an extended span of large diameters, making it a cost-effective and space-saving solution for measuring oversized shafts, rollers, and machined components. Each unit features carbide measuring faces and a ratchet stop for consistent measuring pressure, and is supplied complete with setting standards and a fitted storage case. With models covering ranges from 300mm up to 1400mm (roughly 12" to 80" for inch models), the 3205 series is a practical choice for heavy manufacturing, large-scale machining, and fabrication environments where oversized parts need to be checked accurately.
