Single Action Steel Truss Rod 400mm

Single Action Steel Truss Rod 400mm

This single action truss rod made of steel is a solid and effective solution for adjusting the neck of acoustic or electric guitars. 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 400 mm and comes with a 4 mm Allen key, ready to install.
