Single Action Steel Truss Rod 338mm

Single Action Steel Truss Rod 338mm

This single action truss rod made of steel is a solid and effective solution for adjusting the neck of instruments such as acoustic or electric guitars, short-scale guitars (parlor, 3/4, travel) or even baritone ukuleles. Its design allows precise control of neck relief, ensuring stability and playing comfort.

Steel provides excellent mechanical strength and long-term durability, maintaining its performance even under tension or in humid environments. In addition, the rod is heat-shrink wrapped, improving its reliability: the shrink tubing acts as a corrosion barrier, helps it slide easily into the channel, and ensures a cleaner installation.

This model has a total length of 338 mm and comes with a 4 mm Allen key, ready to install.
