Our RDD Flex Protect Strain Relief Bushings, sometimes known as Lockit strain relief bushings or nylon cable protectors, are designed to provide effective protection and secure strain relief for both round and flat cables. These bushings are manufactured from UL94 V-2 rated Nylon 6/6, offering reliable performance in temperatures ranging from -18°C to 105°C. They are widely used in UK industries such as electrical manufacturing, appliance production, industrial control panels, LED signage, office furniture, and telecommunications. The main benefit is their unique integral nylon spring, which ensures a controlled cable bend radius, preventing kinking or damage at the panel entry. Their snap-in "Lockit" design ensures a secure, tool-free fit, making them a popular choice for installers and OEMs alike. Options are available for both round and flat cables, with a variety of sizes and colour choices on request.
