The
foil fills up the entire circle of the plug. Plugs 00g and larger will have
dome fronts (shown) with the foil in the back of the plug; this provides
magnification with the saddle like a flat flare. Special lengths are not
available for these plugs. We have discontinued small gauge foil plugs...sorry
for any inconvenience. Foil is a flame reactive coloring and can vary slightly
in hue. Now available in Single Flare.
