I want to express my deepest gratitude to the team at LMII.  When I started making guitars 26 years ago, my first guitar was made from wood that I ordered from the LMI catalog (there was no internet back then). Since then, the team at LMI has been nothing short of excellent!  The products and services are second to none.  My only regret is that I waited 26 years to say...THANK YOU!

Adjustable Fingerboard Clamp


The LMI Adjustable Fingerboard Clamp makes easy work of attaching your fretted or unfretted fingerboard to your neck. The AFC clamp includes a blue anodized extruded bar and your choice of either a 10", 12", 16" or 20" CNC precision machined caul set (a caul set contains 7 cauls and bands).

CLAMPSAdjustableFingerboardinUseAFC500The LMI Adjustable fingerclamp in use with bar, cauls and bands.
(Note: The 2 CLF fingerboard clamps shown in photo are not included with this product, but can be purchased separately, here.)

Note: You can simply use the caul upside down for an unradiused fingerboard.

We also sell the 4 caul sets separately for additional radius sizes or for replacement cauls.
