DYMO Rhino Industrial Heat Shrink Tube 12mm – Black/White | 3:1 Ratio, MIL-Spec, -19°C to +135°C

Cable trays in the plant or the comms rack behind the server room — somewhere a bundle of wires is running and nobody can tell which is which. That's a trip-hazard waiting to become a shutdown. This 12mm black-and-white heat shrink tube wraps around the conductor, you print the ID straight onto it, and you're done. Industrial-grade polyolefin, 3:1 shrink ratio, and it carries MIL-M-81531, MIL-STD-22G and SAE-DTL-2353/5 (Class 1 & 3) compliance. Rated from -19°C to +135°C, so it's not going to crack in an unheated shed or warp under a transformer
