Brady M4-187-075-342 PermaSleeve Wire Marker Labels
The Brady M4-187-075-342 PermaSleeve Die-Cut Heat Shrink Labels provide a highly durable wire insulation and identification solution designed for 20 AWG to 10 AWG wire applications. Constructed from UL-recognized B-342 irradiated polyolefin, these heat shrink wire markers are self-extinguishing, flame-retardant, and resistant to extreme temperatures, UV light, chemicals, fuel, and oil. The fast-shrinking material utilizes a 3:1 shrink ratio, ensuring a secure and protective fit around conductors when applied with any standard industrial-grade heat gun.
Each drop-in cartridge contains 80 pre-sized, black-on-white thermal transfer labels featuring a matte finish and a clear identification surface that resists abrasion and fading. This cartridge configuration is mechanically keyed and chipped to ensure compatibility with Brady BMP41, BMP51, and M511 label printers.
