Canon YB2-3356-USC Knob Cover
USCamera made leatherette knob cover plate for the Canon ET-120 WII hood. The adhesive is already applied, just remove the backing, and apply. If you have to dis-assemble the hood lock unit for any reason, the metal cover plate is difficult to remove without damage. This cover is not difficult to remove. Package of 2 leatherette covers. Image shows cover applied to the lock knob. We made this black leatherette cover to replace this expensive original part.
