3M ScotchCode Wire Marker Tape Dispenser with Tape STD

The ScotchCode wire marker tape dispenser is rated for insulation up to 0.145 in (3.7 mm) outside diameter. Above that the pre-printed tape legend won't wrap cleanly, so for larger conductors you need a wider wire marker tape or a write-on marker book instead.

They differ only by character set. STD-0 is MPN 7000006035 and covers the numeric 0-9 legends; STD-C is MPN 7000031515 and carries the alternate standard character set. Same plastic dispenser body, same white tape, same refillable compartments, so pick by the legends your labeling scheme calls for.

It's refillable. The compartments take SDR wire marker refill rolls, so once a legend runs out you reload that compartment rather than replacing the dispenser. You can also have it custom filled with only the characters a given project needs.

The tape is rated to 250 F (121 C). The acrylic adhesive is high tack and resists solvents, oil and water, so it holds in panels, mechanical rooms and damp pulls. It is not UV resistant, so keep it out of direct sunlight or exterior exposed runs.

It's specified for low voltage applications, and 3M lists it for access network work such as FTTH, FTTB and CATV. Use it on control, communications and data conductors. For power feeder phase identification, reach for a heavier vinyl marker tape or a wrap-around cable marker rated for that use.

Each roll runs 2.4 m of 5.46 mm wide white tape, and the ScotchCode dispensers ship 25 per case. That case quantity suits an electrical contractor kitting out a crew or an MRO stockroom issuing one per tool belt.

The tape roll dispenser lets you pull only the length you need and wrap it, so you can build multi-digit numbers on the spot and you aren't locked to the fixed legends printed in a book page. It clips to a tool belt and reloads from refill rolls. A marker book is simpler for a handful of known legends; the dispenser earns its place when you're numbering long runs of conductors and burning through one or two digits far faster than the rest.

RoHS 2011/65/EU compliant without exemption, and manufactured in the United States. That covers the two items most institutional and government purchasing specs ask about on a consumable like this.
