The PanaVise 381 vacuum base PanaVise is a work-holding tool base and head combination designed for use on smooth, non-porous surfaces away from traditional work benches. The base includes a smooth rubber pad and lever combination which creates a vacuum that secures the unit to surfaces. The head assembly component opens to 2-1/2″ (63.5 mm), and clamps down with smooth insulated nylon jaws for gentle holding power. Other features include rugged, yet lightweight construction and a PanaVise “split-ball” adjustment element utilizing single-knob controls for head adjustment on three separate planes (tilt, turn and rotate).

Portable Clamp-free Holding Power

The 381 vacuum base PanaVise is a portable two-piece work-holding tool suitable for hobby, electronics and small home repairs, that consists of the PanaVise 380 vacuum base and the 303 standard vise head. The base component of the unit adheres to smooth, non-porous surfaces via the vacuum action that the rubber pad and flip handle at its bottom create when engaged. The vacuum action creates a stable and reliable working platform that eliminates the need for traditional bench clamps or weighted accessories. The combined unit weighs 2.8 lbs. (1.3 kg), is portable and easy to transport. The rubber vacuum pad is replaceable if its holding power is ever compromised by wear.

The standard 303 vise head assembly utilizes smooth, removable nylon jaws along its opening that measure 2-1/2″ (63.5 mm) by 1/2″ tall (12.6 mm). These secure tough small jobs without scratching and offer excellent electrical insulation and gentle holding power. The overall vise opening width between jaws is 2-1/4″ (57.1 mm). Because exposure to heat sources is common in vise applications such as gluing, circuit board wiring, jewelry making and use around handheld power tools, the vise head assembly is continuously heat tolerance to 200 degrees F (93 degrees C), and intermittent heat tolerant up to 300 degrees F (149 degrees C).

Tilt, Turn and Rotate Functionality

The PanaVise 381 work-holding tool utilizes PanaVise “split-ball” adjustment functionality at the point of 380 vacuum base and the included 303 standard head. Once an item is secured in the vise head, the split-ball system built into the top portion of the base allows a user to maneuver the item along three separate planes using a single knob to make the adjustments. The mobility range of the model 381’s split-ball system is a 90-degree tilt to the side, along with either an angled rotation, or level turn range of 360 degrees. This range of mobility allows a user to rearrange work items into any position, which limits the need to adjust the overall position of the vise or the item within the vise.

Additional Vise Head Options

In addition to the uses possible with the included, the 381 vacuum base PanaVise is intended for use across a wide range of applications and is designed to be compatible with a variety of vise heads. The base works with all PanaVise 300 series vise heads, the PV Jr. model 203 head or any 5/8″ diameter shaft tool accessory.
