Transparent Plastic Safety Horn Cover for Delta Electric Grinders with 17.5-19mm Port

This transparent horn cover is a dedicated safety accessory for a specific range of Delta electric grinders. Weighing 22 grams, it is engineered to screw onto grinders with a 17.5-19mm thread port, creating a protective barrier for the user's entire face. It is intended for industrial and workshop environments where tasks generate hazardous splashes or airborne particles. The clear plastic construction allows for unobstructed vision while providing a defence against a catalogue of workplace dangers, from chemical liquids to metal fragments, making it a practical safety addition for defined grinding and polishing applications.

Features and Construction

Designed with a singular purpose, this cover's features are focused on compatibility and creating a physical shield. Its construction is straightforward, using plastic to form a durable, see-through guard that attaches directly to the tool.

Material and Build

The cover is fabricated from plastic, selected for its ability to form a transparent, rigid shield. This material provides the necessary barrier against impacts and splashes without significantly obscuring the user's line of sight. The build centres on the threaded port, precisely sized at 17.5-19mm to ensure a secure fit to the corresponding Delta grinder, forming a stable base for the protective screen.

Size and Practical Fit

The key dimensional specification is the electric grinding thread port, measuring between 17.5mm and 19mm. This measurement is critical for compatibility, ensuring the cover will attach correctly only to Delta grinder models listed as suitable, including the 100, 200, 275, 285, 300, 395, 398, 400, 770, 800, 3000, 4000, 8100, 8200, 8220, and 4200. The cover's design prioritises a secure fit on these specific tools to function as intended.

Uses and Placement

The cover's application is rooted in industrial safety protocols for processes that involve grinding, polishing, or handling hazardous materials. Its use is situational, recommended for scenarios where the identified risks are present.

Event or Professional Use

This product is suited for professional workshops, manufacturing sites, and metalworking facilities. It is applicable during steel heat treatment, boiler ash delivery, electroplating polishing, and grinding wheel grinding—tasks explicitly mentioned as suitable. In these settings, it serves to prevent damage from the splash of acid, alkali, oil, chemical liquids, metal solutions, iron filings, or glass fragments, acting as a designated piece of personal protective equipment for the face.

Everyday Home Use

While designed for industrial environments, the cover could be relevant for advanced DIY enthusiasts or home workshops where compatible Delta grinders are used for heavy-duty tasks like metal grinding or restoration work that generates similar debris. Its value lies in adding a layer of splash and impact protection where standard safety glasses may be insufficient for full-face coverage.

Benefits and Buying Value

The value of this product is derived from its specialised protective function and tool-specific design. It addresses a clear safety need within a defined context, offering a reusable solution.

Reuse and Low Maintenance

As a solid plastic shield, the cover is built for reuse across multiple work sessions. Its low-maintenance nature stems from the material; it can be wiped clean with a damp cloth after use to remove dust or splash residues. Its longevity is tied to avoiding major impacts that could crack the plastic, making it a durable accessory under normal workshop conditions for the stated tasks.

Why Choose This Product

This horn cover is the correct choice if you operate one of the specified Delta grinder models and require enhanced face protection for grinding, polishing, or handling chemicals. Its primary advantage is its precise compatibility, ensuring it fits your tool correctly, coupled with its stated protective functions against splash, impact, arc, and chemicals. It provides a targeted safety upgrade for a specific set of industrial risks.
