Each strain relief provides the same protection for your power supply cable as the Straight-Thru type AND..
The starin relief exits the cable flush against the chassis, saving space and directing the cable parallel to the chassis.
These strain relievers overcome space limitations and acts as a back or bottom bumper.
Standardize panel design with these strain relievers! Fill unneeded SR mounting holes with Heyco Double D Plugs, page 3-17.
These strain relieving parts are molded of type 6/6 nylon. ASTM D-40660; flammability classification 94V-2; temperature index 125°C. Maximum temperature on the part shall not exceed 105°C.
