A bracket to mount sturdy 64mm diameter rollers on your extrusion (30x30mm). One fastener is M6x12, typical of the scuttle chassis, with your choice of drop-in nut or slide-in nut. The other fastener is M8 x 12mm with a tapped hole in the base of the extrusion for added strength. If you don’t have a tap you can still mount with the M6 screw and gravity will act in your favor to keep things aligned.
