Used to electrically isolate the cable tray from the accessory.
1 x BB912 nylon bushing with 2 x BB940 nylon flat washer allows 5/8" threaded rod to be electrically isolated with hanger angle BA313.
However, the more cost effective way to isolate the BA313 hanger angle is to use 1/2" treaded rod with 2 x BB981 nylon shoulder washers. |
