Vinyl electrical tape in six colours: black, white, red, blue, green and yellow, all in the standard three quarter inch by 66 foot format. Colour is not decoration in this category. Phase identification and circuit coding are why electricians buy more than black, and stocking the full set signals a serious electrical wall.
Single format, six facings, no size confusion at the shelf. It is the definition of an easy reorder, and it pegs beside switches and receptacles or sits at the counter as an add on.
For the rest of the rough in basket, see junction boxes and cords and adapters.
