The TRSA‑1019/G/1/U Heat‑Shrink Cable Marker, supplied by TE Connectivity and available via ENRGTECH in the UK, provides a durable and efficient solution for cable identification. This pre‑printed white sleeve, marked with the letter “U” in bold black, is designed to wrap securely around cables measuring 4 mm to 12 mm in diameter. When heated to above 120 °C, the polyolefin tubing shrinks by 3:1, ensuring a snug, permanent fit that resists abrasion, moisture and flame. Ideal for industrial and telecom environments, these markers arrive in packs of 100 – perfect for installers, engineers and maintenance teams looking for clarity and reliability in labelling.
