The Ultimate in Instrument Neck Bracing
The DragonPlate® Carbon Fiber D-Tube Neck Beam™ has been specifically designed to stabilize instrument necks with its unique D-Tube profile. The D-Tube Neck Beam™ significantly increases bending and torsional stiffness and weighs less than the wood it replaces! Builders also say that the D-Tube significantly improved the tone of their instruments.

Installing the D-Tube Neck Beam™
The D-Tube Neck Beam™ comes in two sizes: 3/4" wide in a straight or tapered profile and 1/2" wide in a straight profile. The 3/4" tapered version is intended for use on thin necks, as seen on certain guitars, while the 1/2" straight is meant for smaller necks like those of a mandolin.
Installing the beam is quick and easy. First, use a 3/4" or 1/2" core box router bit to make a groove in the neck. Then, bond the beam in the groove. For straight beams D-Tubes, the groove should have a constant depth. Tapered beam D-Tubes require a shallower groove at the head, ideal for thin necks.

Replace Typical Approach
The DragonPlate D-Tube Neck Beam™ replaces the typical approach of a truss rod and carbon fiber reinforcement beams with a one-piece insert. Cutting the groove for the d-tube is a much simpler operation and requires less labor than fitting a truss rod and carbon fiber reinforcement strips.
