I bought this arm to mount an 8" x 12" tom off of an 18" bass drum in a bop set I've been working on. I didn't wan't a large ball-type L-arm and prefer to be able to adjust the distance the rack tom is from the bass drum's center. I like the rack tom more in line with the snare drum. This product helped me accomplish that and also gave me some more clearance for my bass drum mounted cymbal arm so that the 21" ride wouldn't hit the rack tom. Sometimes the smallest adjustment can make a big difference especially when dealing with a small, tight set-up.
