Introduced in 1980, the G9021 Floor Tom Legs were originally a tube design but in 1984 they were converted to a solid design. Today it's the floor tom leg used on our standard build option for all USA factory drums. 12.7mm in diameter and knurled on the top half of post, the G9021 works with the G4825 and G9025 bracket or any other floor tom bracket that accepts a 12.7mm size.
