“I received my order today and I just wanted to tell you thanks. The wood is exactly what I wanted, absolutely beautiful, the packaging was great and I'm looking forward to buying more from you. I've purchased tonewoods from other vendors and ebay before, but even the best from them doesn't compare to the quality and value of what I bought from you. Thanks again!”

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).

CLAMPSAdjustableFingerboardinUseAFC500Adjustable fingerclamp in use with bar, cauls and bands.
(The 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.
