Stanley MR55C5 Heavy Duty Riveter

Product Description

The STANLEY MR55C5 is a heavy duty hand riveter designed for setting blind rivets in metal, plastic, and similar materials encountered in HVAC ductwork fabrication, electrical enclosure assembly, plumbing panel work, and general trade installations. Built for repeated use in demanding job-site conditions, this riveter delivers consistent clinching force across standard rivet sizes. At 1.43 pounds, it is lightweight enough for extended overhead or confined-space work without causing undue fatigue. Electricians, HVAC technicians, plumbers, and sheet metal workers reach for this tool when a permanent, vibration-resistant mechanical fastener is required and welding or threading is not practical.

The MR55C5 suits residential and light commercial applications where blind rivets are the fastening method of choice. Common use cases include securing duct flanges, mounting electrical boxes and brackets, attaching access panels, and assembling support structures. The tool is sold individually and is well suited for contractors who need a reliable backup riveter or a dedicated unit for a specific crew member.

Key Features

• Heavy duty construction rated for repeated use on demanding job sites
• Lightweight at 1.43 pounds, reducing fatigue during extended or overhead work
• Compatible with standard blind rivet sizes used in HVAC, electrical, and plumbing trades
• Manual hand operation requires no power source or compressor
• Compact form factor suitable for confined-space and tight-clearance installations

Compatibility

Designed for use with standard blind pop rivets commonly found in HVAC ductwork, electrical enclosure, and light structural assembly applications. Specific compatible rivet sizes and mandrel types are not stated in the available product data; confirm rivet head and shank diameter compatibility before ordering.

Installation Notes

This tool is used by sheet metal workers, HVAC technicians, electricians, and plumbers to set blind rivets without access to the back side of the workpiece. Ensure the correct rivet diameter and grip range are matched to the material thickness before beginning work. Wear appropriate eye protection, as spent mandrels eject during the setting process. No power source is required, but keep the nose piece and jaw assembly clean and lubricated for consistent performance.
