New, never been installed White Speaker Grille.  Change your old 'not-quite-white-anymore' grilles, stained by smoking, dented by your grandchildren, or just dusty beyond hope due to old-age.  Make them look as good as brand-new.  Your stereo will love you.  Your mother or wife will be so happy and proud !!  

The actual Diameter of this is 6 3/16 inch (6.1875").  It fits over the 5 1/4 inch (5.250") commonly defined ceiling speaker.

I recently bought a set of replacement speakers new, but I re-used my existing custom painted grilles.  These were New, fresh out of the box just 30 days ago.  I'll never use them, and it's time to re-plenish my ham radio mad-money account.  Let's make a deal !!
