Wayne's Audio Turntable Periphery Stabilizing Outer Ring

I second the super easy to use comment. Takes mere seconds. 

btw,

IF your cartridge is a LOW RIDER, the clearance between the bottom of the cartridge body and the top of the ring may be very small, or not enough, so that the beginning of track 1 cannot be played, the cartridge body must move 'in' enough for it not to contact the top/inner edge of the ring.

OK I’m going to try it and report back. Cheers for all the input. 🙏🏼

Clearaudio Outer Limits is an alternative. I have one on a second system deck and it works dandy. The spider alignment tool is a bit quirky to use. On the main table I use a VPI Periphery Ring which works just dandy as it is designed to be used with their 12” platters. 
 

No experience with the Wayne’s Audio product although it looks very well designed. 

A very ugly solution.  Not elegant at all.  I would hate to have that in my system.

Just bin the warped records.
