Standard convoluted charcoal foam with sizes of ½ valleys and 1 ½ peaks by 12” X 38” inches thick that can be cut to fit a standard rifle case. The two pieces fit together are a total of 2” thick and should be fitted into the case top to bottom as shown. The entire piece can be cut with a carving knife, but should be first sized to the case. By fitting the solid piece top to bottom, this insures that both pieces will meet and fit together.
