This parallel keeper is said to be quickly adjusted from approximately 1 to 4.2 inch to hold parallels against the vise jaws as the vise is open and closed during workpiece loading/unloading.

“Parakeep” is what Rimeco Products Inc. calls the adjustable parallel keeper it developed. The company says the device can be used with any standard set of parallels on any machine vise, holding workholding parallels in place while the vise is opened and closed during normal use.

The Parakeep has a spring-loaded housing with an adjustable screw that enables a machine setup person to quickly adjust the device’s parallel stabilizing mechanism with each new job. It serves as an alternate method to conventional means (using different length springs, scrap material, washers and so on) to hold parallels against the vise jaws as the vise is open and closed during workpiece loading/unloading. An individual Parakeep unit has a work envelope of 1 to 2.25 inches, while the kit covers 0.25 to 4.25 inches.
