E-12 Mahogany Internal Reinforcement 740x17x6 mm

E-12 Mahogany Internal Reinforcement 740x17x6 mm

The Mahogany Internal Reinforcement E-12 is designed to strengthen the joint between the back and the sides in stringed instruments, providing structural stability without compromising sound transmission.

Made from mahogany, a wood valued in lutherie for its lightness, stability, and ease of working, this 740 x 17 x 6 mm straight-format reinforcement is suitable for a wide range of construction techniques and designs.

Internal reinforcements — also known as linings, kerfing, or blocks — are key components that reinforce the junction between the sides and the top or back. They help prevent deformation and improve the instrument’s resonance and tonal response.
