These clamps slide into the T-tracks on the bed of the Vertigo CNC and can be placed at various points on the machine. This allows you to securely clamp various different sizes of material.
Each clamp consists of a T-bolt, a washer, and a wingnut.
The Vertigo CNC comes with a selection of clamps, but you can buy additional ones here. The clamps can also be used in other applications that use 3¼ inch T-slot track.
