lightweight soundhole clamp, 4″ (10 cm) throat depth

We embraced new materials to make the lightest AND strongest soundhole clamps ever. These clamps are made of glass fiber Vydyne (an extremely strong automotive resin) that helps reduce weight and increase rigidity. They’re also made in the USA.

If you’re wondering if they’re as strong as their metal cousins, you’re in for a treat. They deliver tons of clamping pressure right where you need it with no twist or flex. The large, easy to grip thumbscrew gets to work fast for time sensitive repairs, essential when using quick-setting hot hide glue. You have fingertip control for the exact amount of pressure you need. Self-leveling feet quickly get a grip on any surface.

We offer additional soundhole clamp cauls (SM2016) that snap onto the feet to evenly distribute pressure, making it less likely to cause dents on bridge pads and braces. The clamps have softened edges, no hard corners, and a smooth overall finish; you’re less likely to damage guitar tops with the slightest bump like you can with metal clamps.

Each clamp opens 2″ wide and moves in and out of the soundhole easily, and we designed a new wedge shape that lets you put them closer together for more pressure; perfect for re-gluing a bridge or a loose brace.

The 4″ clamp is ideal for tenor and baritone ukulele bridges or cracks, the 5″ clamp is the right length for gluing bridges, and the 6″ is perfect for gluing braces, soundboard cracks, and more.
