These clamps reach where others can't. Ideal for clamping bridges and braces through a soundhole.

Our popular soundhole clamps feature strong steel frames, light weight and slim profiles for multiple clamping through the soundhole of a classical or steel-string guitar. Ideal for clamping bridges and braces through a soundhole. Available in four lengths. Leveling screw gives extra support for clamping bridges and braces. The 7", 9" and 11" models have a special leveling screw to help support the clamp's weight and prevent unwanted bending of the soundboard.

The shorter clamps give increased clamping coverage at the guitar's bridge and shoulder areas.

Our soundhole clamps also have knurled thumbscrews, height-adjustable jaw screws for clearance of internal braces, and jaw feet that swivel to conform to uneven surfaces (maximum opening is 1-7/8"). Each clamp is 1/2" (12.7mm) wide.

Prevent dents: Check out our Soundhole Clamp Cauls that snap onto the feet of these clamps for a larger clamping footprint, padded surface, and grooves that make it easier to clamp on braces.

Soundhole Bridge Clamps

By fullwedge from Cornwall on Hudson, NY
(Customer's Reviews) Monday, March 25, 2013

Seemed a bit flexible at first. Leveling screw binds when clamp is under tension. But set the leveler first and then the clamp and it works like a charm. Lightweight, essential repair/builder tool.

5-Inch Soundhole Clamps

By JDR-Craftsman from Burke, VA
(Customer's Reviews) Sunday, January 13, 2013

These clamps did an excellent job in gluing the bridge on a tenor ukulele. Adding 3/8 inch self-stick felt pads to each clamp ensured that I'd get no dents or scratches.

Great Clamps

The 5" sound hole clamps I recieved from Stewmac are perfect for acoustic guitar repairs. Great clamps easy to use and fully adjustable.

Perfect Clamp

By Scott Reeves from Simsbury, CT
(Customer's Reviews) Friday, December 07, 2012

These clamps are perfect for clamping a bridge on a classical guitar. The smaller soundhole of the classical guitar is difficult enough; its disposition farther from the bridge makes depth an issue. If you add a fingerboard extension for a 20th fret, you have a serious problem, especially if you have large hands. The leveler supports the clamp perfectly to prevent distortion of a thin (2.2mm) top. The light construction is not a problem if the parts require minimal force to fit.

I used 3 of the 7 inch clamps to secure the bridge after gluing. They worked well.

All the right sizes for the job!

Nice light clamps, perfect for glueing bridges and loose braces!

5 in clamps

By ChrisG from Winnipeg, MB Canada
(Customer's Reviews) Thursday, September 13, 2012

These, the smallest of the set, are still too large for ukuleles...except for Baritone ukes. Silly me, I bought 3! Pehaps I can cut a piece out of each arm and weld it together again!

soundhole clamps

By Brad H. from Carlsbad, Ca.
(Customer's Reviews) Friday, August 17, 2012

This is the only clamp I have found that will fit through the soundhole, clear the braces and clamp the bridge.
One is not enough and the smallest size just barely worked, but did. I am ordering 2 more of the medium sizes for future projects. Great service and quick shipping from Stewmac.

Works As Advertised!
