Numbered labels for controller wires

The Klein Tools 56250 Wire Marker Book gives dry service areas numbered labels from 1 through 48. In an irrigation controller cabinet, those numbers can help station wires line up with controller stations and valve-box notes.

The book format keeps the labels together so the next station check begins with a clean numbering system.

Keep labels dry and readable

Wire labels belong where the surface and location match the product directions. For controller cabinets, place labels where they can be read without tugging on wires.

Outdoor valve boxes may call for waterproof tags or other outdoor labeling. Keep dry wire markers with the controller and weather-ready tags near the valve station.

Pair wire numbers with route names

Numbers are useful when they connect to plain route names. Write station 1, front lawn or station 2, herb bed in the controller record so a number becomes a place in the yard.

That record can also include valve-box location, solenoid notes, and rain-sensor details.

Good match
