Thanks sdx,

What's the make and model number of you home? Let's call the manufacturer and ask how to remove the drain.
(You could have photo shopped that picture and put some screws there. Mark always wins.)

Harold, you came across a thread from 2009. They probably are done with this issue by now.

Bob,
Sdnx revive it yesterday. He has same problem.

Sdnx,
Are there any notches in the inner edge of the outer ring?

I would be prying the strainer out by getting a small, thin flathead screwdriver and prying in between the strainer and the strainer body, not by prying up on the strainer itself. If you kinda treat it like a paint can lid and slowly go all around the strainer, prying lightly as you go all around, that strainer should pop out (and then you can flatten things back to normal). Just my final thoughts on this!

Well, my final thoughts except one for Harold: Nyah-nyah...I win this time (see image)!! :) Have a good night all!!

So you think you won, just watch how low your temperature goes tonight.

Yup! Went pretty low...again! Been a pretty harsh winter, for sure!! More freeze ups, and some bad ones at that, than I have ever seen!!

I though that was you I saw along the side of the road trying to get your truck started. I turned it off with my remote control.

How do you find these neat pictures?

Better late than never? I have a 2014 Cavco Park Model, and the shower drain is exactly the same showed by the original poster of this thread. Found this thread because the drain is running slow and wanted to do the baking soda, vinegar, hot water treatment. There are NO screws holding the hair-catcher to outter drain. Have tried prying it up gently using a screw driver while making my way around the catcher. No luck other than bent flimsy metal now. I finally had to work the baking soda down with my fingers which resulted in a good amount of it clinging to the underside of the hair-catcher. Threw up my hands at this point and just slowly poured the vinegar and hot water solution over it. Not as effective and a lot messier, but I don't wish to end up having to replace the entire mechanism. Maybe calling in a plumber next time in order to learn just how to remove that hair-catcher without destroying it or the outter part is in order now.

Again, there are NO screws involved with the inner mechanism.

I am having the same issue in my manufactured home. No screws and the cover does not appear to unscrew or pop off despite gently trying to do this. I've attached a picture below...
