Plumb Site® Dual-View™ Vial

Our Plumb Site® vial viewer allows the user to read the plumb vial in the traditional way – the side-view – as well as from a front-view position.

The Plumb Site® Advantages

Completely eliminates parallax error
Improves the accuracy reading of the level because the vial can be viewed from the front
Provides continuous line of sight from the reflected image through the top of the vial for a greatly enhanced field of vertical vision
Eliminates neck and back strain since there’s no need to view the plumb vial from the side of the level
Increases efficiency and saves time (up to 30% on large vertical alignment jobs)


A New Level of Visibility. OPTIVISION™ is a Kapro invention that creates the effect of strong color definition around the spirit level’s horizontal bubble, in stark contrast to the white vial background and clear liquid. The color contrast makes the bubble edges significantly easier to see, for fast and accurate placement between the vial’s reading lines.

The OPTIVISION™ Advantages:

Highly visible red bubble edge
Fast placement between reading lines
Easy viewing with tilted vial
Precise leveling results
