3M 7000144114 5 Inch Type 27 Grinder Guard

Product Description

The 3M 7000144114 is an optional Type 27 grinder guard designed to allow 5-inch abrasive products to be run safely on compatible disc sanders. The guard replaces the standard 4-inch guard and expands the usable disc size range on supported machines. It ships as a complete kit that includes the 5-inch guard body, a 1/4-20 external bolt, and a 1/4-20 internal nut, so no separate hardware sourcing is required. This guard is installed by abrasive equipment operators and tool technicians performing routine accessory upgrades on disc sanding equipment.

This guard is intended for use with the 3M 4-inch to 5-inch 1 HP Disc Sanders (part number 28408) in industrial, fabrication, and production grinding environments. It is suited for applications where operators need to step up from 4-inch to 5-inch disc capacity without replacing the base sander unit. This accessory is commonly found in metal fabrication shops, maintenance facilities, and manufacturing settings where disc sanders see regular use.

Key Features

• Type 27 guard profile for compatibility with flat and depressed-center disc applications

Installation Notes

Disconnect and de-energize the disc sander completely before removing the existing guard or installing this replacement. Use appropriate hand tools to seat the 1/4-20 hardware securely without overtightening the plastic or cast guard body. Follow ANSI B11 and applicable OSHA machine-guarding standards when mounting abrasive tool guards. Confirm the guard is fully secured and all fasteners are snug before resuming disc sander operation.
