Termination coaster for ICC jacks

I have one that works on ICC, I got it from Graybar. It is for their Allen-tel line and fits perfect for every jack I have ever used. Its red and oval in shape.

a keystone coaster ?

As someone who does occasional ethernet wiring and is a tool catalog junkie I've never heard or seen anthing like this.

How much to they cost ?

I picked one up at Graybar recently (after finding out about it here) for less than $4.00. For this coaster to work, the punch-downs need to be on TOP of the jack, with the tab-side facing down.
