Callaham tremolo arms are made from  turned, ground, and polished stainless steel. When combined with Callahams Enhanced Tremolo block are nearly unbreakable.

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.)

This "64" length is 5 1/4" from tip to bend without tip installed and is the standard Callaham arm.

Specification:

• LENGTH: 5.25" (133MM) APROX
• THREAD: 10-32 UNF
• TIP COLOR: PARCHMENT - MINT GREEN AVAILABLE ON REQUEST
