Marking tools are used to define cutting and alignment references in masonry, installation, assembly, and renovations. Chalk lines allow straight lines to be drawn on large surfaces, and plumb bobs help check verticality on walls, partitions, and structures.
Chalk lines are selected by cord length (30 or 50 m), body material (aluminum or technical polymer), and chalk reservoir, variables that affect cord tension, mechanism durability, and marking visibility.
Professional plumb bobs are chosen by weight, format (nut type), and magnetic base when working on metal profiles. Marking chalk is usually available in 360g or 1kg, with good visibility and adherence on common construction surfaces.
- Chalk line cord length
- Body material and mechanism resistance
- Plumb bob weight and format
- Type and visibility of marking chalk
- Intensity of use in layout
