Rittal AS 4055.143
The Rittal AS 4055.143 is a metallic enclosure accessory intended for producing round punch cut-outs in stainless steel panels. It is designed as a durable tool for making precise Ø 43.2 mm holes in metal sheets, supporting installation tasks where neat, repeatable openings are required.
The tool is constructed from robust metal for long service life and reliable performance in industrial settings. It is compact and relatively lightweight, which simplifies handling during installation tasks. The punch produces consistent round cut-outs suitable for mounting switches, connectors, or conduit fittings.
This product is intended specifically for punching round cut-outs; it is not suitable for cutting other hole shapes or for use on very thick or hardened steels beyond the tool’s intended capacity. For precision work on thin or delicate panels, a specialist cutting method may be more appropriate to avoid deformation.
Mark the desired hole location on the stainless steel panel and secure the panel to prevent movement. Position the punch over the marked spot and apply steady force according to the tool’s instructions or using compatible pressing equipment. Remove any burrs after punching and verify the hole diameter and edge quality before installing components.
Use appropriate personal protective equipment, clamp panels securely, and deburr edges after punching to ensure safe, clean installations when working with the Rittal AS 4055.143.
