## Common ground
All options refer to mounting or fitting brackets, used to secure objects to surfaces.
## Options at a glance
**3926.30 – Made of plastic material**
- **Defining trait:** Constructed primarily from plastic (e.g., polypropylene, ABS).
- **Typical examples:** Plastic wall anchors, cable tie mounts, lightweight shelf brackets.
- **Best fit when:** The bracket is lightweight, non-conductive, and used in low-stress or indoor applications.
**8302.41 – Made of base metal**
- **Defining trait:** Constructed from ferrous or non-ferrous metals (e.g., steel, aluminum).
- **Typical examples:** Steel wall brackets, metal shelf supports, industrial mounting arms.
- **Best fit when:** High strength, durability, or load-bearing capacity is required.
## Key differences
| Feature | 3926.30 (Plastic) | 8302.41 (Base Metal) |
|---------------------|--------------------------|----------------------------|
| Material | Plastic | Metal (e.g., steel, aluminum) |
| Strength & Load | Low to moderate | High |
| Corrosion Resistance| Good (if non-polar plastic)| Varies (may rust without coating) |
| Electrical Conductivity | Non-conductive | Conductive |
## How to choose
- Is the bracket made of plastic? → 3926.30
- Is it made of metal (e.g., steel or aluminum)? → 8302.41
## Overlaps & pitfalls
A bracket could be partially plastic and partially metal (e.g., metal screw with plastic base), but the primary material determines classification. If unclear, prioritize the dominant material by weight or function. No option is inherently more important—choose based on the **main structural material**
