RDD Right Angle Strain Relief Bushings
RDD Right Angle Strain Relief Bushings (also known as RDD Lockit strain reliefs, right-angle cable bushings, snap-fit bushings) are robust cable entry components designed to secure and protect both flat and round cables exiting panels at a right angle. Manufactured from UL94V-2 rated Nylon 6/6, they resist temperatures from -18 °C to 105 °C and snap-fit into Double-D mounting holes, preventing rotation and eliminating cable kinking.
Widely used across UK industries such as electrical cabinet manufacturing, control panels, data centres, telecoms enclosures, machinery builds, and renewable energy installations, their key advantage is tool-free installation combined with reliable cable retention. Available in varied sizes to accommodate different panel thicknesses and cable dimensions, they suit flat ribbon cables, power cords, signal leads and more.
Available Materials & Style Options
- Black Nylon 6/6, UL94V-2 rated
- Available for Flat cable ("F" suffix) or Round cable ("R" suffix)
- Snap-fit "Lockit" design with multi-finger locking
- Compatible with various Double-D hole diameters and panel depths
Key Features & Benefits
- Right-angle exit reduces stress and prevents cable kinking during sharp bends.
- Lockit finger design ensures tool-free, snap-fit installation and secure panel retention.
- Double-D hole shape stops bushings rotating under cable load.
- Heat-resistant Nylon 6/6 material is UL94V-2 flammability rated and UL recognised—suitable for harsh environments.
- Accepts a range of cable dimensions (both flat and round), making them versatile for mixed-cable panels.
- Multi-step locking accommodates different panel thicknesses for a flush, finished fit.
- UL and CSA recognised component, reinforcing compliance and safety credentials.
Common UK Use Cases
- Control panel builds - providing neat, secure cable exits for power and control wiring.
- Server and telecom racks - protecting data leads and ensuring tidy cable routing.
- Industrial machinery sheeting - offering cable protection against oils, dust and vibration.
- Renewable energy enclosures - preventing cable fatigue in inverter and battery panel installations.
- Electric vehicle charging units - managing heavy cable loads exiting charging panels.
