Brady PermaSleeve M21-375-C-342-YL is a heat-shrink sleeve label cartridge for marking wires and cables. Its black print on yellow material makes the identification easy to distinguish on a cable run or in an electrical installation.
Made from heat-shrink polyolefin, the continuous sleeve has a 3:1 shrink ratio and measures 0.375 in in supplied diameter by 7 ft long. Brady lists it for wires in the 12 AWG–4 AWG range. The sleeve contracts around the conductor when heat is applied, giving the printed identifier a close fit.
This cartridge is compatible with BMP21, BMP21-LAB, BMP21-PLUS, IDPAL, LABPAL, M210, M210-LAB and M211 printers. Brady identifies electrical, wire and cable labeling as its application, including military, aerospace, defense and transit wire marking.
