HELP ME! question for those who daisy chain their sadowsky preamp!

[ShowKing]

I'm having trouble with my rockcable 5 daisy chain..
the metal tip is 1.0mm and it is short by 0.2mm!
the power supply keeps falling out of the pedal so easily because it's just too loose.
it works fine on my boss pedals but for the sadowsky pedal it needs to be more than 1.2mm at the metal tip.

can anyone that use a daisy chain for their sadowsky recommend me a different daisy chain that will fit snuggly into the sadowsky preamp?

thanks

anyone?
