How this estimate works
Each quantity comes from a stated rule of thumb applied to your answers. For a typical factory, machines or control panels (5 control panels, 10 machines, 20 motors), these are the rules and the items they point to:

- Machine cable runs: 60 ties per machine
- NR-1/2R R-type cable clamp, 1/2 in (12.7 mm) cable, 12 mm wide
- Clamping runs to machine frames: 20 per machine
- NR-TM-25 Adhesive tie mount, 25 × 25 mm base, 6.2 mm tie slot

We add 10% for waste and offcuts, round up to whole packs of 100 and whole rolls, and show a low to high range because real jobs vary with routing, spacing and spec. Your drawings and spec sections beat any rule of thumb: send them with your quote request and we'll price from them.
