## Features and Benefits

### Custom Structures:

If you have Custom Structures made for your Cat® Equipment, staying with the same design and materials in the event of a replacement part is the best way to ensure a proper and integrated fit.

### Fire Suppression System & Components:

Heavy equipment features moving parts, along with substances like oil and gas that are highly flammable. A fire on any of your Cat machines could be catastrophic. Protect your equipment and personnel with suppression systems and components designed to stop fire at its source.

### Frame – Heavy Fabrications:

Heavy fabrication structures are the heart of Cat equipment. Purpose-built to meet specifications. You can be assured your Cat equipment is secure and stable, protected from damage, supports weighty loads, and ready to perform.

### Frame – Light Fabrications:

Cat light fabrications are built specifically for Cat equipment. When Cat aftermarket structures are installed, they fit with precision, allow safe movement on/off and from one area to another, cover and protect the cab and crucial areas from gravel, mud, and debris.

### Guard Assembly Structures:

Shield tanks, tracks, belts, sensors, fans, cylinders, engines and important items from damage, debris, and dust. External cab guarding adds a layer of protection against damage, weather, and theft.

### Other Covers & Supports:

Replacement covers and supports offer the same high-quality materials and dimensional precision as factory originals. Ensure performance with guaranteed dimensional accuracy. Protect your investment by always choosing genuine Cat parts.

### Scraper Elevator and Ejector Systems:

Genuine Cat replacement parts for your scraper elevator or ejector systems ensure your systems will operate with optimum performance and help you move material efficiently. Supports and covers that are damaged or worn out put the moving components of these systems at risk of damage or failure. Find the proper replacement parts from Caterpillar that keep these systems protected and functioning as designed.

### Grease Lubrication Systems:

Lubrication provides a seal that protects critical parts from dirt and the elements. Cat lube systems and components are held to the highest standards of quality, reliability, and durability to assure equipment is working, and working properly.

### Tanks & Components:

Count on precise fit, same as factory. Cat replacement tanks, gauges, and caps have been systematically engineered into the design of every machine to ensure optimum fit, safety, and storage capacities.
