It is a Gallagher scale with tru-test load bars and platform. It bolted to the alley of our portable tub/alley/chute in the background of the first photo. Two sliding gates keep animal in alley until weighed then off to the head gate. Love it come weaning and implant time for feeder cattle. Records are quite valuable. Rural Mfg in freeman, SD is where we bought this set-up. They will customize them just the way u want....pretty awesome crew.
