This component can be retro fitted to a TRA8003 Heavy Duty Scenery Carrier to enable the scenery Carriers on a curved track to be cord operated.The arm is designed to bolt to the holes on either the side of the scenery carrier.

The vertical part of the arms carries two cord clamps, one on the outer side of each arm.

The two arms are connected by a plate which serves to divert the cord from both directions up to the individual cord clamps.

The arms are designed to position this plate on the cord line and permit it to pass between TRA and UBM19 capstan pulleys.
