Vital Parts Lockit Strain Relief Products

Why Use Strain Relief Bushings?

Strain Relief Bushings are used when a cable enters a product or device to lock it into the shell/chassis and prevent it being pulled out. Commonly seen on products such as toasters, lamps, and industrial machinery, they are pronominally used to support power cables entering a device that are then terminated inside, giving power to the product.

Due to the nature of these products being in homes, commercial premises, industrial workshops, etc., it is critical that should the product fall or the cable be pulled that the cable does not come free from the product, leaving potentially electrically live cores exposed to touch. Using a strain relief bushing effectively locks the cable into the product at point of access.

These products are available in a number of different variants, from the industry standard through to the quick-to-install Lockit range, as well as the new water-tight IP rated versions that not only lock the cable into the product, but make the entry point water-tight, which removes the need to use a second sealing component such as a Cable Gland or Grommet.

The products are designed to exceed UK's 35lb (15.7Kg) pull out test, making them a reliable and essential component for both industrial and consumer electronics.
