### From the Manufacturer

The PanaVise 391 micrometer stand is a work-holding tool bundle designed to provide a convenient, stable and easily-manipulated platform from which to use sensitive micrometer measuring devices. The 391 micrometer stand contains the PanaVise 385 micrometer head and the PanaVise 305 low-profile base. Additional features of the 391 micrometer stand include: the ability securely hold circuit boards and other small items, and a load control knob that allows adjustment of held items along three separate planes (tilt, turn and rotate).

##### Hold a Micrometer Exactly Where You Want It

The PanaVise 391 micrometer stand is designed to help obtain error-free readings of the widths of small machined parts and other objects, using the calibrated screws of micrometers. The 391 micrometer stand consists of two PanaVise components: the 385 micrometer head and the 305 low-profile base. The PanaVise 385 micrometer head is 3-1/8" (79.8 mm) tall and weighs 0.23 lb. (0.1 kg). The head has a 5/8" (15.9 mm) shaft with which it mounts to the PanaVise 305 low-profile base. The upper end of the head has a side twist jaw lined with two thermoplastic Delrin pads. The jaws of the 385 micrometer head open from 0 - 1/2" (12.7 mm) with the high stiffness and low friction of the Delrin pads aiding in the accuracy of readings. The 385 micrometer head has a 15/16" (24.1 mm) throat depth. This allows the head to effectively clamp the frame of an inserted micrometer into place, freeing one hand to hold the edge of a part within the anvil and spindle of the micrometer while the other turns micrometer's thimble knob to take a measurement. The PanaVise 350 low-profile base is 2-1/2" (63.5 mm) with a base diameter of 4-5/16" (109.5 mm). The low profile of the base allows a user to keep an item comfortably close, and closer to the work bench. The bolt circle at the bottom of the base contains three pre-drilled holes countersunk for use with 1/4" (6.3 mm) flat head screws (sold separately), to secure the base to a work surface. Alternatively, the 1.3 lb. (0.6 kg) weight of the 350 low-profile base can maintain stability and stand alone.


Split-ball adjustments allow micrometers to be positioned to take the most accurate readings. View larger.

##### Tilt, Turn and Rotate Functionality

The 391 micrometer stand utilizes PanaVise single knob "split-ball" functionality at the point of contact between its base and head. Once the two components are connected and an item is secured, the split-ball system allows for maneuvering that item along three separate planes (tilt, turn and rotate) with a single-load control knob locking the head firmly in place. The complete range of mobility possible with the model 391's split-ball system is a 90-degree tilt to the side, along with either an angled rotation, or a level turn range of 360 degrees. This mobility range allows a user to rearrange items being worked on into any position, limiting the need to adjust the overall position of the vise or the item within the vise.

##### Multiple Vise Head Options

Although the included 385 micrometer head is intended as the head option of the PanaVise 391 micrometer stand, the 391 is also designed to be compatible with a range of vise heads. The included 305 low-profile base works with all PanaVise 300 series vise heads, as well as the PV Jr. model 203 head, or any with a 5/8" diameter shaft, allowing a user to expand their work-holding tool's capabilities as dired.
