RDD Straight Thru Strain Relief Bushings

Our RDD Straight Thru Strain Relief Bushings are part of the Lockit range from Heyco, which are designed to lock your cable firmly in position and snap fit into your panel hole. Produced to fit double d shaped holes (hence the name RDD) these work to eliminate the risks of rotation after installation, which could cause damage to your cable. Manufactured from a UL94V-2 rated Nylon 6/6 these are capable of resisting temperatures between -18°C to 105°C and are available for both flat and round cable types, with specific electrical knock out hole sizes also available.
