Steel Stopper Pin Added to Shutter Release Bar to Fit Peri-Pro Film Processor for Better Performance

To make the Shutter Release Bar (RPI Part #ATB600) last longer, we installed a stainless steel stopper pin. The pin prevents wear.

Another benefit of the newly added stopper pin is that it interacts with the plate at the time the film drops. This interaction creates a noise loud enough for the user to hear, thus becoming aware that the action has completed its cycle. In addition, for easy replacement identification, the ATB600 now has the RPI part number molded right into the part.

One final note about the ATB600. Be sure to take note of the condition of the bar and the area surrounding it. Both should be kept clean because if it is not cleaned on a regular basis, the shutter release bar will not activate the shutter plate and the films will not drop into the processor as they should.
