Taurus Cupholders question

Im trying to instal them and used the write up but it seems un clear to me. I know you remove the thing that holds in the stereo but what do you use after you take the bezel out to keep your stereo safe?

what do you mean by “safe”?

What i mean by “Safe” is that it wont be sliding in and out since it dosent have a bezel to hold it in. i am just confused on how it would stay in the console nice and tight
