Callaham Stainless Steel Tremolo Arm Standard Fender Length Full Threads
We offer 3 different length arms with either our virtual pop-in thread or a traditional full thread. If you are using our enhanced block, you should use our virtual pop-in arm. A traditional full thread arm is really only for those still using their stock Fender trem block.
Callaham tremolo arm lengths are measured from the tip to center of 90 degree bend. The Standard Fender length is 6" from tip to center.
The threads on Callaham tremolo arms are UNF 10-32. The short thread on the Virtual Pop-in Arm is just to keep the arm from being pulled out of the block. (Can only be used with our Enhanced blocks.)
