48H307 - Walter 48-H-307 Power Cord Strain Relief Bushing

Maintain Tool Safety with Genuine Walter Replacement Parts

The Walter 48H307 Cable Bush is a critical component designed to ensure the operational safety and longevity of your Walter Surface Technologies power tools. Often overlooked, the cable bush—also known as a strain relief or cord guard—plays a vital role in the electrical integrity of handheld power equipment. Located at the point where the electrical power cord enters the tool housing, this component absorbs the mechanical stress and flexing that occurs during daily operation.

Without a functioning cable bush, the power cord is susceptible to acute bending against the hard edges of the tool casing. Over time, this friction and stress can lead to the insulation fraying, exposed copper wires, and potentially dangerous electrical shorts or shocks. The 48H307 is engineered to OEM specifications, ensuring a perfect fit that seals the housing entry and provides the correct amount of flexibility. By distributing the bending force over a longer arc, it prevents the cord from kinking and breaking internally.

For industrial MRO (Maintenance, Repair, and Operations) professionals, using genuine OEM parts like the Walter 48H307 is essential for maintaining compliance with safety standards. Generic replacements may not fit the housing recess correctly, leading to loose cords or compromised dust protection. This part is manufactured from high-quality, durable rubber materials capable of withstanding the harsh environments of metalworking shops, including exposure to grinding dust, sparks, and oils.

Key Technical Benefits

• OEM Precision: Designed specifically for Walter tools to ensure a tight seal and proper retention of the power cord.


• Electrical Safety: Primary defense against cord insulation damage and short circuits at the handle entry.


• Durability: Resists cracking and stiffening over time, even in demanding industrial conditions.

When servicing your fleet of Walter grinders or finishing tools, inspecting the condition of the cable bush is a standard procedure. If signs of cracking, dry rot, or separation are visible, immediate replacement with the 48H307 is recommended to prevent unscheduled downtime and ensure operator safety.
