The following heads are compatible with the 300 Standard Base, the 305 Low-Profile Base, and the 381 Vacuum Base. A new or additional head will add extra productivity to your existing PanaVise, or start here to build your own! All stems at 5/8" (15.9mm) in diameter. All our vises and work holding devices come with a "lifetime warranty."
