The T-Jaw
A Pat. Pend. Vise Workholding accessory and suite of various clamping components. The T-Jaw allows workholding of delicate workpieces that are hard to hold. Thin walled parts, plastics, parts that can't be held by the traditional method of applying a clamping force from one direction. The T-Jaw adds a second direction of clamping, thereby reducing the risk of damaging the workpiece by excessive pressure from one direction of clamping.  So for holding very thin walled parts, apply light pressure from the vise’s jaws, and apply a second direction of light pressure, from the T-Jaw.
The T-Jaw vise kit mounts directly to a vise, any vise. Various styles of T-Jaws are available for vises.
Quick Mount T-Jaws, Tall T-Jaws, Side Mount T-Jaws, Direct Mount T-Jaws, T-Jaws with removable jaw pads,  or machineable jaw pads.
T-Jaws can be mounted to T-Slot Blocks
