Hinfudor Guitar Fret Leveling Kit with 16-Inch Beam, Notched Straightedge & Gauge

Some guitar owners only need to check string height, others want tools for fret leveling and neck measurements in one set. The Hinfudor kit is aimed at the broader setup task. Could one kit cover those different checks? It includes a leveling beam, a notched straightedge, and a combined fret rocker and action gauge.

Why it’s worth it

The practical appeal is having several related checks covered without assembling each tool separately. The 16-inch leveling beam is paired with 12 self-adhesive sandpaper strips in six grits, from 120 through 1000. That range gives you options for fret leveling and other sanding tasks described for the beam, while the 4mm notched straightedge helps assess fretboard flatness and fret-wire levelness.

For a home setup, the combined rocker and action gauge adds a way to spot uneven frets and read string height using its marked ruler. The set is also described for bass, banjo, and mandolin, so its stated use is not limited to standard guitars. It suits you if you want to take on basic measuring and leveling work yourself and are comfortable learning how each tool is used.

Highlights

The beam is made from precision-ground aluminum alloy, weighs 1.35lbs, and has a curved handle and rubber end caps. Its listed sandpaper grits are 120, 240, 320, 400, 600, and 1000, with two strips of each. The kit also includes a velvet drawstring bag and masking tape.

The notched straightedge is 16.9 inches long and supports 24.75-inch and 25.5-inch scale lengths. Its notched edge is intended for checking fretboard flatness, the full straight edge is for checking fret-wire levelness. The 2-in-1 tool has four fret-rocker edges measuring 4 inches, 3 inches, 2 inches, and 1.3 inches. Its ruler provides readings in inches, millimeters, and 64ths.

This is a more consolidated approach than buying a separate beam, straightedge, rocker, and action gauge. The tradeoff is that the set is focused on leveling and measurement tasks, it is not presented as a complete collection for every kind of fret repair.

How to use it

Use the measuring tools to assess the neck and identify areas that may need attention before working with the sanding beam. The straightedge checks fretboard or fret-wire alignment, while the rocker can help locate a high fret and the ruler can measure string height. The beam and adhesive strips are intended for leveling and sanding work. The kit is described for guitars, basses, banjos, and mandolins, but the notched straightedge’s stated scale lengths are 24.75 inches and 25.5 inches, a detail worth considering for your instrument.

What to clarify

What comes in the kit? The listed contents are the 16-inch beam, 12 replacement sandpaper strips, a notched straightedge, a 2-in-1 fret rocker and string action gauge, masking tape, and a velvet drawstring bag.

Which instruments is it intended for? The product details name guitars, basses, banjos, and mandolins, among other stringed instruments.

What does the ruler measure? The built-in ruler is marked for readings in inches, millimeters, and 64ths, the gauge is described for checking string height and other setup dimensions.

Buying verdict

This kit makes sense if you want a single set for fret leveling and common neck and string-height checks, and you value having several measuring tools together. It might not be a great match if you only need one occasional measurement tool or are looking for a kit explicitly covering a wider range of fret-repair steps. The most useful fit check is whether the listed tools and the straightedge’s scale lengths match the work you plan to do.
