Trucks and finials
A flag truck built for concealment towers.
The SwingArm Truck is a replacement revolving flag truck for concealment and stealth flagpole cell towers. It swivels with the wind, flips up for maintenance and fits towers 24 to 73 in across. The Adapter Plate mounts it on an existing tower without a rebuild, and the gold Finial Ball finishes it.
Which truck do I need?
Match the spindle thread and the tower diameter
If the tower has WindBands, add 1 in to the diameter. Where two sizes overlap, use the smaller one. Not sure of the thread? Most towers are UNC, and we confirm with you before invoicing or shipping.

- Adjustable sliding beam in 1 1/2 in steps fits a range of towers, including bump-outs
