Frankford Arsenal Rotary Tumbler Sifting Caps are designed to fit the Platinum Series Rotary Tumbler and the Rotary Tumbler Lite. With these wire mesh caps the solution can be poured out of the drum without losing any stainless pins. The robust design allows the user to rinse the brass and media in the drum then dump the liquid out without making a mess or scattering pins and brass everywhere. Convenient 2 pack will fit both ends of the Platinum Series drum so the drum can be held over a sink or bucket while water is poured in the top rinsing the brass in one easy operation.
