Have an odd what I think is GAL door roller. It's a single pivoting roller, and no stationary roller. Does anyone know the part number and/or if it is still available? If not will a two roller vertical set up work? it looks like a MOM assembly just without the stationary roller.
I just found we have a job with one of these old dover rotary units (1957) and one of the more seasoned guys in our company said it's an early GAL product and not sure of availability. The clutch used is stationary and doesn't have a retracting arm so you may not be able to use a stacked roller set up with both rollers on it. You could probably use a dover /tk clutch and add ramps to pick the retracting bar
