Balance Rite BRF-QR Forward Weighted Pool Cue Extension System, Lucasi Quick-Release

I have a 7 year lucasi custom lze29 cue with a unilock quick release joint will this fit my cue. it says quick release but not unilock quick release?

will this fit a cuetec prestige series? i think all cuetecs have the same joints so is anybody using this on a cuetec already?

It's uniloc right?

How do know what pin size I need???
