Description of this instrument for sale

The Alberti C-Clamp

This c-clamp was designed for the assembly and restoration of musical instruments but has wide application anywhere a lightweight, precision, quick-setting (and releasing) clamp is of use.

The clamp slide runs through binding plates which are, in turn, depressed by a knurled pressure screw. Clamping can be accomplished with one handed operation by pushing the slide down through the binding plates with your thumb until the clamp is held to the work and then additional force is applied with the pressure screw.

The clamp can be set with thumb pressure alone or tightened to 50 pounds of force if necessary. Loosening the pressure screw and releasing the binding plates allows the slide to be fully retracted in seconds.

CNC machined from 2024 T4 aluminum with a stainless steel slide running in a brass bushing and removable anodized aluminum swivel pads, all parts of the clamp can be replaced or serviced. The swivel pads are mounted with friction retainers so they hold their position and can be separated from the clamp should you glue them to your work.

The pressure screws have an internal hex socket so the clamps can be nested next to each other and tightened with a key.
