## Long description

Rittal AS 4055.742 is a red accessory designed for stamping and marking applications in electrical enclosures and industrial cabinets. Supplied as a 9.5 mm round component, it is intended to be used with compatible dies and stamping tools to assist in panel identification, labelling and organized cable or equipment marking during installation and maintenance.
Advantages
The accessory is lightweight and colour-coded to allow quick visual identification within a set of stamping tools or during on-site work. Its 9.5 mm round shape provides a consistent marking size for labels or punched guide points. Compatibility with a range of dies enables punching of round holes from 6.6 mm up to 21.5 mm in busbars when used together with appropriate dies and stamps.
Suitable for
 Panel identification and labelling in electrical enclosures
 Marking and organisation of wiring and terminal positions
 Use with stamping tools and dies for controlled round punches in busbars
 Maintenance and installation work where colour-coded accessories speed up tool selection
When it may not be suitable
This accessory is intended specifically for stamping/marking operations and does not function as a standalone cutting or drilling tool. It requires compatible stamping dies and a press or hand-stamping tool to produce holes or marks.
For applications that need non-round shapes, larger structural modifications, or high-volume automated punching without manual tool compatibility, a different tool or accessory may be more appropriate.

How to use
Install the accessory into the compatible stamping tool according to the tool manufacturer's instructions, then select and fit the appropriate die for the desired punch diameter.

What to consider before purchase
 Confirm compatibility with your stamping tool and dies.
 Verify that the 9.5 mm round size meets your labelling or marking requirements.
 Consider the required punching diameter range (6.6 mm to 21.5 mm) and whether additional dies are needed.
 Assess whether colour-coding and lightweight construction fit your on-site workflow.
