Before the invention of heat shrinkable cable accessories, cables were repaired using mechanical fasteners, such as clamps, ties, and straps. These fasteners were used to secure the cables in place and provide strain relief. However, these fasteners were not always reliable and could become loose over time. Cable attachments were developed as a more reliable and secure way to repair cables. heat shrinkable cable accessories provide a tight fit around the cable, which helps to protect the cable from environmental elements, such as moisture, dust, and vibration.
