Some masking systems are fully manual, but most are motorized. Motorized systems may be chain-drive or cable-driven, with either a sprocket or cable drum attached to the motor shaft. For motorized systems, stops are programmed for each format. For manual systems, the stops must be marked somewhere on the masking system (ex., tape may be applied to the side of the screen frame or the top of the skirt to denote how far the sides should be brought in). | Some masking systems are fully manual, but most are motorized.

It’s a good idea to keep spare fuses on-hand for the masking motors, since masking frozen in the wrong position may require show cancellations. | It’s a good idea to keep spare fuses on-hand for the masking motors, since masking frozen in the wrong position may require show cancellations. | ||
