Thomas & Betts WM-0-90 Wire Marker Books

The WM-0-90 book carries the legend range 0 through 90, split across the pages as 0-45 and 46-90. So one book covers every whole number in that range, which is what you want for numbering conductors in a panel or pulling a circuit count up to 90 without having to buy several separate single-number packs.

The marker stock is a vinyl coated cloth tape made to resist abrasion, oil, water, and dirt, so it holds up in mechanical rooms, pump rooms, and dusty service spaces better than paper or plain adhesive labels. It is a wrap-around cloth marker, not a printable polyester tag.

They are sold each, but with an order multiple of 10, so quantities go up in tens. A full inner pack is 10 books and the outer carton holds 240. For a single truck stock order, 10 is the smallest quantity.

Ten pages per book. The markers are printed on cards bound under a cover that keeps them clean until you peel them, and the book itself is 3 x 5-1/2 inches so it rides in a shirt pocket while you are on a ladder.

Yes, the WM-0-90 is RoHS compliant, which is the item most often queried on government, healthcare, and education submittals for consumable marking products.

Use the number book when your labeling scheme is circuit or conductor numbers, which is the usual case for branch circuits and panel schedules numbered sequentially. The WM-0-90 covers 0 through 90 in one pocket book. If your scheme uses phase letters or equipment designations instead, you want a letter legend book rather than this one; the Thomas & Betts wire marker book line is offered in a range of sizes and legends, so pick the legend that matches the drawing.
