Thanks sparky589, yes I've seen the full range of Quik lok accessories. The problem is I need a shallow support for my LCD monitor behind the keyboard. The stand is against a wall so there is only about 16cm between the back of the keyboard and the wall. I am fitting the accessory bar to the stand, but the existing products from Quik Lok need additional space behind the stand and are very deep. Think I will probably make something myself to clamp on the accessory bar.
