Thomas & Betts Self-Laminating Wire Marker Book

They ship blank. The legend on the WM-BW series is (Blank), so you write your own circuit numbers, panel IDs, or device tags on the marking area and then fold the clear laminating tail over the writing. If you need pre-printed numbered or lettered legends, these are not the books to order.

Three marking areas are offered: 3/4 x 1.25 inches (WM-BW34) for short tags, 1 x 2.75 inches (WM-BW5) for a medium legend, and 1 x 4.875 inches (WM-BW3) when you need room for a full panel-circuit-device string. Longer marking area also means a longer wrap, so the bigger cards suit larger conductors and cable bundles while the 3/4 inch card fits fine control wire.

The self-laminating style has a printable write-on panel plus a clear tail that wraps over the writing, so the legend is sealed under vinyl instead of exposed. That holds up in panels, pull boxes, and mechanical rooms where handling, dust, or moisture would smear a plain marker. If you only need sequential numbers on control wire and the tags live inside a dry enclosure, a pre-printed number book is faster since these WM-BW cards are blank and have to be written out.

Sold by the each, with an order multiple of 10 books, 10 to an inner pack and 240 to the outer carton. That makes it a sensible standardization item for an MRO storeroom or a fleet of service trucks: one carton covers a crew for a long time, and you can break out inner packs of 10.

Yes, the WM-BW wire marker books are RoHS compliant, which is usually what a government, healthcare, or education submittal is asking for on an identification product.

The WM-BW books have a print legend area covered by the clear protective section, so the marking area takes a written or printed legend before it is wrapped. There is no printer model or compatibility stated for these cards, so treat them as a write-on card book for field marking.
