Which type of tools include dividers, squares, and chalk line reels?

Layout tools are designed for marking and creating precise lines and measurements on materials, which is essential in pipe fitting for accurate installation. Tools such as dividers are used to measure and mark distances, ensuring that fittings are placed at the correct locations. Squares are instrumental in ensuring that angles are accurate, which is critical for proper alignment and connection of pipes. Chalk line reels allow workers to snap straight lines over longer distances easily, aiding in alignment and layout tasks.

In contrast, measuring tools focus primarily on quantifying dimensions, typically including devices like tape measures and calipers. Cutting tools are specifically aimed at physically cutting materials, such as pipes or tubing, and include saws and pipe cutters. Finishing tools are related to the final touches on a project, such as sanding or polishing, which are not relevant for initial layout tasks. Therefore, layout tools encompass the specific category that includes dividers, squares, and chalk line reels, facilitating the setup and preparation of pipe installation.
