StewMac Bridge Clamp Caul

About This Item

For gluing acoustic guitar bridges
Evenly distributes clamping pressure across the acoustic bridge. Works with one clamp or multiple clamps. Shaped and padded underside conforms to the contours of most bridges.

Use a single clamp: Apply one strong clamp at the middle of the caul. We recommend our Large Swivel Handle Clamp. Add extra pressure at the bridge ends using the caul's built-in wing clamps using the wrench provided.

Use multiple clamps: When the job requires the extra pressure, the caul's level surface provides a good footing for three or more clamps. The wing clamp adjusting screws sit below the surface so they won't interfere with additional clamps.

Two indexing screws mate with the bridge pin holes to hold the caul in place while you work (wrench provided). These screws have an added benefit: with the caul held upside-down in a vise, the screws keep the bridge from sliding while you scrape and score the underside before gluing.

  • Size: 5-7/8" x 1-1/4" (149mm x 32mm)
  • Solid aluminum
  • Rubber pads are non-reactive with instrument finishes
  • Two hex wrenches included for wing clamps and index screws

The Bridge Clamping Caul is included in our Acoustic Bridge Tools Set, for removing and installing acoustic bridges and bridge plates (bridge pads).

Bridge caul - works great!


Verified Buyer

I bought this tool because I have several old guitars with lifting bridges, not to mention that this is such a common problem but it seems like a good tool to have. I used it in conjunction with a 7 in guitar sound hole clamp also from Stewart MacDonald and it worked great. The bridge I reglued using this caul is still fastened tight even with the strings on under tension for several weeks. Very happy with this purchase!
