A cable nail clip 12mm is a small, typically metal fastener used for securing electrical cables or wires to walls, floors, or other surfaces. The "12mm" refers to the size of the clip, specifically the diameter or the size of the cable it can accommodate, which is 12 millimeters. These clips are typically used in electrical installations or DIY projects where wires need to be fixed in place to prevent damage or ensure safety.

Key features of cable nail clips:

• Material: Often made of galvanized steel or plastic, offering durability and resistance to rust.
• Size: The 12mm size can hold cables that have a similar diameter, such as certain power cables or low-voltage wires.
• Ease of use: They are typically easy to install with a hammer by driving the nail into a surface, securing the cable in place.

These clips are useful for organizing cables, protecting them from wear and tear, and keeping them neatly arranged along walls or under floors. They are commonly used in homes, offices, and various construction or renovation projects.
