Which tool is recommended for pulling heavy cables from the bottom up?

The recommended tool for pulling heavy cables from the bottom up is a tugger. A tugger, or cable puller, is specifically designed to handle the significant strain and weight of large cables, allowing for efficient and safe installation. It uses mechanical advantage to generate the necessary pulling force, making it ideal for heavy-duty applications, such as those often encountered in telecommunications and data installations.

Fish tape, while useful for guiding lighter cables through conduits, lacks the capacity and power to manage the weight and resistance of heavier cables. Wire strippers are tools designed for prepping wires, specifically to remove insulation, and are not applicable for pulling cables. Cable testers are essential for verifying the integrity and functionality of cables once installed but are not involved in the physical installation or pulling process. Thus, the tugger is the appropriate choice for the specified task.
