Applying a clip sleeve wire marker is simple with our special Quik-Wand applicator included with every sleeve. Just place the flared shoe end of the wand against the wire and push sleeve onto the wire. Split sleeve with chevron locking design snaps on the wire so it won't slip or slide. Numbers, letters, symbols and blank sleeves are available in 12 different sizes to fit virtually all wire gauge sizes. - Combination packs (prefix SCNC) contain 10 wands, one wand each of 0 through 9. Alpha packs (example: SCN07-A-M) contain 13 wands, one wand each of A through M or N through Z.
