RDD Straight Thru Strain Relief Bushings

RDD Straight Thru Strain Relief Bushings, also known as nylon panel bushings or Lockit bushings, are essential components for providing strain relief and cable protection where round wires pass through metal or plastic panels. These bushings are widely used across UK industries including electronics manufacturing, control panel assembly, automation, and general electrical engineering. Their main function is to secure and protect cables, preventing unwanted movement or abrasion that could lead to cable damage or system failures. Manufactured from durable UL94V-2 rated Nylon 6/6, these bushings are available in a variety of sizes to accommodate different cable diameters and panel thicknesses, and feature a straight-thru design to support uninterrupted cable routing.

What are RDD Straight Thru Strain Relief Bushings?

RDD Straight Thru Strain Relief Bushings are designed to lock securely into a double-D panel hole and clamp around the cable as it passes through the panel. This ensures the cable remains firmly in place and protected from sharp panel edges, minimising strain on the connection and reducing the risk of electrical faults. Their robust nylon construction offers resistance to impacts, chemicals, and temperatures ranging from -18°C to +105°C, making them suitable for demanding industrial and commercial settings in the UK.
