Dixon make an excellent heavy duty rack available from Drum-tec in Germany and you can add to it to make custom set ups.
I found a UK manufacturer of mild steel tubbing and they Chrome plated some 2.8 meter telescopic uprights for my rack and I have t-bars on the top of them and I have Led Par cans and effects lights hung from them. It makes a great show for a Solo Drummer.
I will find the link when I get a chance. Have a nice easter everyone.
