Wheatland Ag, Inc. has a complete hardware system to operate curtains conventionally by rolling up or by letting down to open. We use a pipe driven system instead of cables and pulleys, which we feel gives a more trouble free operation. Lift ropes are used every six feet with one handed adjustment. Seat belt webbing or galvanized tubing is used as wind restraints.

Manual operators come in either 8:1 or 14:1 gear ratios and can easily roll up 175’ and 225’ curtains, respectively (6’ height). We have two types of electric operators: one kind meant to be run by thermostat to keep constant temperature, and the second that moves faster, meant to run up or down by a simple toggle switch.
